Gadget Watches: Some companies are trying to invent these, in response to, as of The New Tens, the smartphone and tablet being far more popular personal accessories than the watch.
Gaia's Lament: Unfortunately, due to climate change (though some people dispute this), pollution of various kinds, overfishing, nuclear contamination in some areas, and other forms of environmental damage.
Gargle Blaster: Some bartenders do make drinks like this in real life, as either hangover cures, challenges ("if you can drink this you have free beer for a week"), or as ways to dispose of low-quality or undesired liqueurs.
Gaslighting: Very unfortunate Truth in Television. Engaged in by abusive partners, high-demand abusive coercive religious groups, and occasionally even by law enforcement or medical professionals who wish to make someone seem or feel unbalanced or troubled, either to themselves or others.
Gayborhood: Quite a few of them exist in the US and around the world. California alone has Hillcrest in San Diego, West Hollywood in Los Angeles and Castro Street in San Francisco.
General Ripper: Same as above. Many but listing them is probably not a good idea.
Genius Bruiser: Sumo wrestlers and technical wrestlers. Some US NFL players, before chronic traumatic encephalopathy sets in (or if it does not).
Genius Ditz: Some people whose profession it is to entertain others tend to be this, because entertainers are not generally thought of as "smart." One example is Dee Snider's testimony regarding the PMRC - a Hair Metal singer is brought before the US Congress looking dragged in from a late show and hung over, and the PMRC had apparently expected him to make a fool of himself and bolster their cause. Instead, he provided an eloquent and factually-backed defense of free speech while also implyingthatTipper Gore was a closeted sadomasochist.
Genocide Backfire: Why genocide isn't only one of the worst evils possible, but one of the most pragmatically stupid evils as well. There are always survivors, and even if somehow there isn't any, genocide does not go unnoticed forever. Note the American genocide of Native Americans, which seemed to be successfully swept under the rug until the survivors and their descendants and their supporters began to speak out...
The reason a lot of innocent people or nonviolent/petty criminals get into serious trouble with the police. (There are a very specific set of actions, behaviors, rules, and similar one must follow when dealing with police officers if one does not wish to end up arrested or dead.)
Similarly, the reason a lot of kids are set up as delinquents, at least in very strict school settings: people working in the education setting (especially administrators, behavioral specialists, etcetera) have a very specific idea of what "good kids" are and what "bad kids" are. When profiling based on race or appearance gets involved, this gets very nasty fast.
The reason those who fall victim to politics or intrigue in any environment (whether an office or a fandom or a house or whatever) often do - there's warning signs of such being in play, and if you miss those signs, your time in that environment will be short and miserable unless you learn how to play.
The reason why, if you seek treatment for a mental health issue, you need to know your issue and direct your own treatment plan if at all possible, so you can remain proactive in your treatment and be seen as a candidate for recovery rather than becoming a pinball in the system.
The reason why you should know enough about cars to at least have a vague idea of what's wrong when your car needs repair. The difference between "the battery is dead" and "it won't start and I have no idea why, it was making a funny noise first maybe?" is sometimes around a few thousand dollars if you run into a shady enough mechanic. Same thing goes for computers, or for anything else where repairs are expensive and generally arcane to most users.
Knowing how to deal with authority, if not to appeal to it, to get it out of your life so you can go on your way.
Understanding the signs of abusive or toxic environments to make yourself less vulnerable to them and to avoid getting into them.
Understanding anything you need professional help with, if not as well as the professional, well enough to work with them as a team rather than be seen as a passive consumer at best and a sucker at worst.
Gentle Giant: Israel Kamakawiwo'ole, a Hawaiian singer famous after his hit "Somewhere Over the Rainbow". Andrť the Giant. A great many others.
George Jetson Job Security: Oklahoma, Indiana and an increasing number of other states now have "fire-at-will" laws which allow employers to fire employees without explanation or advance notice, except as mandated by federal laws.
Ghost Shipping: The variant of a widow/er not being able to let go of their late spouse/partner/lover if they die is very common - it is a result of deep or complicated grief, especially at a sudden or senseless loss.
Giant Poofy Sleeves: The "leg of mutton" sleeves of the 19th century. The puff-and-slash sleeve of the Renaissance. The revival of leg o' mutton sleeves in the 1980's.
Gift Giving Gaffe: Happens with gifts that are incredibly inappropriate (e.g. it's probably not a good idea to give your boss a vibrator unless you work at a sex toy company, or to give kids alcohol or tobacco), insulting (never give anyone bodybuilding/diet/fashion/housekeeping/health books or items unless that's a personal interest of theirs and they've specifically asked for those), Too Much Information (e.g. gift certificates for colonics or waxing), or outright homophobic/racist/sexist.
Gigantic Gulp: Huge drinks are quite common in some places. Anti-obesity advocates seek laws to reduce them in some of those places.
Gilded Cage: Getting or being rich has its own concerns and problems - and some people do feel trapped by their upper-class status, and in some cases are prohibited from things they want to do due to maintaining decorum or out of self-protection.
G.I.R.L.: Not as common as it used to be - internet gender split is around 50/50 now - but often done by law enforcement and others doing stings of pedophiles and similar predators, and also becoming one of the most common ways for a transgender person to begin passing, especially since for some, it is the only way to pass.
God and Satan Are Both Jerks: Optionally add "and neither really exist" and you have the view of some atheists, and also the view of some variants of non-theistic Satanism.
God Emperor: The Imperial Japanese believed this as part of a nationalist fascism. It didnot end well.. Post World War II, the divinity of the imperial family remains an important part in some strains of Shinto, but not all (some Shinto followers see the divinity of the emperor as a political imposition on their beliefs that corrupted the faith), and is technically acknowledged but is far more ceremonial than anything else, except to right-wing nationalists - the Japanese equivalent of Neo-Nazis.
God Is Good: Most forms of Christianity believe this and all will profess this (even the above kinds that accidentally imply God Is Evil will proclaim that is actually good). Also the primary belief of all forms of Islam and all forms of religious Judaism. Combined with "and doesn't exist," you have atheists who believe religion is a positive influence even if false. Combined with "and walked away from it all," you have Deists. Combined with "there are many gods and many/the one over them all is good/we are all gods and innately good" you have much Neo Paganism.
Godwin's Law: Try to find one comment section on a controversial topic without one Nazi comparison. YOU WILL FAIL.
Godzilla Threshold: When something will kill people or, especially, kill lots of people, anything is preferable. Whether it's getting someone addicted to drugs so they don't kill themselves or cutting off their gangrenous limb on a personal level, or shooting dead the guy with an assault rifle trained on his family, or destroying the streets of a city to turn them into flood control channels or considering aiming nuclear weapons at an incoming asteroid...
Going by the Matchbook: Pocket litter, as it is called, can provide very useful clues as to where someone was - but it can also provide false leads (the person went somewhere but it was irrelevant), dead ends (e.g. the person went somewhere but nothing happened there) and plenty of other misdirections.
Going Cosmic: The result of the use of some types of recreational drugs.
Going Native: Expatriates, and people who marry into or work closely with other cultures that are far different than the one in which they were born and raised.
Going to See the Elephant: For people who have to tag along on shopping trips or similar when they don't need to or want to buy anything. Going to an event or party only to find out that it has been canceled.
Gone Horribly Right: Most weapons, from guns to nukes. They're made to threaten people and to kill people - and that they do.
Good Cop/Bad Cop: Actual cops do this routine - which is one of many reasons that you need a lawyer if you ever find yourself under investigation, whether you are innocent or not. It's also used in other settings. The thing to keep in mind is they both want the same thing from you.
Good Is Not Nice: Especially using the "manners" and "tone" definition for "nice," since a common tactic of those who want to maintain repression or the restriction of civil rights (and of abusers in general) is to pick on someone for manners or tone rather than address the argument itself or the person's needs.
People who have done good deeds have situations where being nice and polite doesn't always achieve a good goal, especially if it involves in hurting those they love (i.e, a good parent must punish their child and a good friend must rebuke the other if they're following to the wrong path). One way or another, this doesn't say that people won't enjoy doing this their loved ones.
Good Is Not Soft: Because in dealing with certain people (psychopaths and harmful sociopaths who commit violence against others, rapists/pedophiles unable to suppress their urges or redirect them into fantasy alone, predators in general) and in regard to one concept (genocidal racial/ethnic/national hatred, as when it gets any sort of a foothold in a society, that society is on the slippery slope to the same place the Nazis were), protecting society and its most vulnerable requires vigilance, strict laws, and total rejection of justification.
Good Old Fisticuffs: Street brawlers will usually win against martial artists (unless the martial art is something like Krav Maga or capoeira that originated with needing to be useful in street fighting) due to their being Combat Pragmatists or being unpredictable.
Good Versus Good: What happens when people who have ethical goals come into severe conflict or drama over how to achieve them. Some big examples being the debates over anything related to any given minority group from women to GLBTQIA people to racial minorities, to whether recreational drugs and recreational use of drugs should be handled via the legal system (prohibition) or the medical system (legalization and treatment)... very few people involved in any of those debates are what could be considered "evil," but all see different ways needed to achieve "good."
Goomba Stomp: Quite a few animals can actually be killed when jumped on, although that applies to mostly smaller animals.
Go Out with a Smile: If someone's suffered from a painful terminal illness and is finally getting to die, and/or someone who feels their life has been lived to its best and they're ready to die dies. Usually involves euthanasia because most means of dying without drug assistance are very painful...
Goshdang It To Heck: Mormons unless they're "jack Mormons" and even some of those, are absolutely famous for this. Some other religious people (generally of more conservative sects) at least in public.
Gotta Kill Them All: Some unbalanced people or killers make "kill lists." Other people write fake "kill lists" as a fantasy or as a joke - which is not a very good idea, because fantasy and joke kill lists, though they're never meant to be acted on seriously, are taken seriously by law enforcement in many places, and you can face felony charges for threatening, harassment, terrorism, or even conspiracy to commit murder, even if none of the targets see the list or even if some see it and actively acknowledge it as a joke.
Got Volunteered: Being signed up as a volunteer for something one actually doesn't want happens quite often, especially in military and office settings.
Government Drug Enforcement: When people are legally ordered to take psychiatric drugs or take anti-alcohol or anti-opiate medications. Only slightly less controversially, chemical castration for serial rapists and serial pedophiles.
Grail in the Garbage: Some incredibly expensive and rare items have been thrown out or left for thrift shop collections or yard sales, for example, only to be found later by people who understand their value.
Granola Girl: They exist - just go to any "natural health" or "yoga" or similar event, or read the comments over on Natural News and you'll see them.
Grass Is Greener: Why people try to change their place in life. Sometimes it's not, per the Aesop, other times it actually is and people regret not trying for it sooner or even commit suicide over the despair of realizing it is too late to make said changes. One of the greatest sources of depression in Real Life.
Gray Rain of Depression: Rainier and snowier areas tend to have higher representations of several mental illnesses. Being born in a snowy winter northern climate (e.g. Canada, Scandinavia) is correlated to a five percent increase in development of schizophrenia.
Gray and Gray Morality: Ninety percent of interpersonal conflict is this. No one is seeking to irreparably harm or kill the other, no one is seeking to do anything that is definitely and truly unethical - both sides are seeking what they find to be their moral and ethical goals, except said goals highly differ.
Great White Hunter: Jim Corbett was a naturalist and conservationist who hunted several tigers and other big cats that had turned man-eater. Many far less ethical examples exist: they're called poachers.
Grievous Harm with a Body: People have been killed or seriously injured when someone committing suicide by jumping lands on them. Human stampedes/crushes also achieve their fatality from this: the weight and strength of the living people trying to escape and the sometimes already dead bodies crushes and suffocates more people to death. This is also the reason you should not sleep with your baby in the same bed - an adult's body can crush or suffocate an infant's without even awakening the adult until it's too late.
Groin Attack: Attacks to the genitals are indeed paralyzingly, fetal-position-inducingly painful and will knock most any guy (and sometimes gal) out of commission.
Groupie Brigade: Actors, musicians, and many other famous and notorious people have these. Generally they tend to appear at shows, parties, and other events related to their person of interest, and are quite more varied than the stereotype: some can be respectful of the stars and of other fans. Others, not so much.
Grows on Trees: Quite a lot of food does grow on trees. Tree nuts, almost all fruits that aren't tomatoes, berries, or melons, and avocados.
Grumpy Old Man: Everything from life experiences parking someone firmly on the cynical side of the sliding scale to illnesses such as dementia can make some seniors very much this trope.
Guide Dang It: Learning a foreign language. Cooking. Almost anything involving computers, though this may change. Anything related to repairs.
Guns Are Worthless: Most definitely notTruth in Television after around the late 19th century (and one of the great debates of the 20th century onward is if they have become too not-worthless), but the very first guns (e.g. muskets and the like) were incredibly difficult to load, fire, and reload, had a very slow fire rate, and were often likely to blow up on the shooter. Until firearms technology and training improved, a skilled archer was a far more dangerous ranged attacker than a shooter, and guns were near-useless melee weapons, because in the time it would take to load and fire, the enemy soldier's sword would already be through your heart.
Guns in Church: The open carry movement invokes this on occasion. Obviously, anyone committing a crime with a gun also invokes it.
Guys Are Slobs: In cultures that encourage men to be uncultured slobs and that hold up slobbishness and lack of education and culture as "manly" and alternately writes off cleanliness, culturedness, education, and refinement as "feminine" or "gay," men obsessed with proving their heterosexuality and masculinity will often become uncultured slobs.
Had to Come to Prison to Be a Crook: Prison is rarely rehabilitative, and the lack of real rehabilitation and recidivism gets higher with the security and the punitiveness (e.g. this happens even more in medium and maximum security than in minimum security). In prison, criminals meet more hardened or more clever criminals and jailhouse lawyers - learning how to stay on the outside longer, how to commit different crimes, and similar for the next time - but will likely go back. It also doesn't help that a felony record stays with someone - making it impossible in some instances to find legitimate employment or housing.
Hair-Trigger Temper: Borderline personality disorder, bipolar disorder in manic or mixed episodes, intermittent explosive disorder, some forms of dementia, and some forms of epilepsy can cause this. And then there are just the people who don't have any specific mental illness, but are just that angry all the time and waiting for something to lash out at. These can be found anywhere from a Flame War to road rage incidents, and they make up a large portion of people convicted for assault with a deadly weapon, aggravated assault, aggravated battery, attempted murder, and murder.
Hanging Judge: Some have existed, and some do exist. Also, the "mandatory minimum" sentencing system in the US can turn any judge into this when it sends someone to prison for 20 years or more for a nonviolent crime.
Happy Marriage Charade: More common in the past, but loveless arranged marriages and celebrity marriages can be this, because an immediate divorce is forbidden by religion or would be tabloid fodder or blackmail fodder. Also can happen in more homophobic cultures, where a gay man and a lesbian or a bisexual man and bisexual woman pretend to be in a happy heterosexual marriage to satisfy society's needs and protect themselves from harm or outing - and have their same-sex relationships in secret.
Harmless Villain: Some people designated as villains in real life may not be very harmful. This is very much something on which the mileage of many people may vary, so no more will be said and no examples will be given.
Has Two Mommies: Or two daddies - same-sex couples are parents in some regions of the world.
Hate Plague: Mob mentality and methamphetamine abuse are on one end of the spectrum in that while neither are actual "disease," they spread virally and produce hatred, paranoia, and violence. On the other end, for actual disease, we have rabies and possibly toxoplasmosis.
Hates the Job, Loves the Limelight: Especially because in some corners of acting, the music industry, and other parts of creative media, it's considered cool to maintain an attitude of being "above it all," and cynical, distrustful, and jaded.
Have I Mentioned I am Gay?: Sometimes necessary for gay people who avert All Gays Are Promiscuous because of the annoying omnipresence of that stereotype even in GLBTQIA circles and the idea that if you're not having lots and lots of sex, you're not really for real. The variant of alluding to one's bisexuality is even more common because without it, one tends to get pigeonholed as "100 percent straight" or "100 percent gay" and therefore potential partners are repelled.
Headbutting Heroes: Firefighters with different plans of fighting a fire/rescuing people from something. Doctors who heavily disagree on a diagnosis or course of treatment.
Headdesk: Sometimes this does happen in real life. Or the object isn't a desk... everything from walls to pianos to computer keyboards have occasionally gotten this treatment.
Healing Herb: Many herbs do have medicial properties, if used properly.
Healing Potion: In the subverted sense, liquid medications. They won't likely save your life, but everything from Pepto-Bismol to Nyquil will definitely help you feel better if you need them.
Also in a subverted sense, red wine, with the flavonols in it being powerful antioxidants that slow aging, prevent cancer, and possibly even prevent Alzheimer's, the fermentation enhancing their effect, and the alcohol at small levels reducing stress and the damage stress brings to the body. The trick is to consume just enough that you get the benefit of the flavonol compounds, but you don't get too much bad effect from overconsumption of the alcohol, which can obviously cancel out all of these benefits and provide even more risks. Needless to say, not a good idea for The Alcoholic or anyone else who can't stop at one glass per day/per every other day.
Healing Shiv: Many surgical and medical tools are objects that in the hands of anyone but skilled surgeons and doctors, can cause horrific injuries or death (and even do in their intended surgical and medical uses sometimes).
Hešvy MŽtal ‹mlaut: Used by quite a few metal bands, though phasing out of interest because of overuse.
Heavy Voice: Can happen due to thicker vocal folds in overweight people, or due to testosterone whether as therapy or as illicit steroid use.
Heel Face Door Slam: Because if an organization is bad enough and violent enough, or a friend or acquaintance is, their response to percieved betrayal to be something else/to leave may well be violence.
Heel-Face Revolving Door: Mercenaries, private armies, and others whose allegiance to any side is bought. Also very common in Gray and Gray Morality conflict - which much real world conflict is - when people who were once "heels" to one side of the conflict become "faces" to the other, or vice versa.
Heel-Face Turn: People who have left racist and other hate groups, or violent sects.
Heel Realization: Often the only reason why people who do bad things truly change - they realize they were wrong and what they did hurt people. The point of everything from interventions for addicts to abuser treatment programs is to force these, and arrest and imprisonment are a less successful way of trying to force these. A darker version is when a high demand coercive group tries to force one of these on someone who really isn't a bad person doing bad things, to convince them they are and joining the group is the only path to salvation.
Heir Club for Men: Inheritance in many parts of the world until the 20th century. In a combination of Older Than They Think and Fair for Its Day, Islamic sharia law was actually one of the first legal systems to buck the tradition of male-only inheritance, by demanding women recieve at least some direct inheritance.
Hereditary Hairstyle: Because many boys and men unconsciously or consciously model their fathers or brothers in regard to fashion. Especially common before unique and stylish fashion for men became common. Far less common in women and girls for a variety of reasons.
A variant of it exists in Visual Kei with "legacy hairstyles," which aren't between blood relatives (usually) but which are either so linked to a specific artist that wearing them signifies a connection/support/liking for that artist, or signifying of a specific need/style.
Heroic Resolve: Human beings can, in some of the worst emergencies and disasters, find strength they never knew they had to save others' or their own lives.
Heroic RROD: Unfortunately, many human beings (especially if engaged in an activity they enjoy or feel they absolutely must do) can push themselves past their bodies' limits leading to major, sometimes disabling injuries or even their own death.
Heroic Sacrifice: People have sacrificed their own lives to save others' lives. A depressingly common example comes from mass shootings in the US, where people have been shot and killed by the heavily-armed assailants while trying to stop him/protect others.
Heroic Self-Deprecation: Real people who did good things feel bad about themselves, especially if the "good things" came at a cost of human life or suffering or even property or money, or if they weren't done soon enough... among many other reasons.
Heroic Vow: These are a required part of some organizations and the like.
He's Got a Weapon!: If you hear any of the variants of this, immediately flee as far as you can in the other direction while trying to stay out of sight, and call for Emergency Services if you possibly can.
Hesitation Equals Dishonesty: Sometimes, with especially bad liars. Other times it simply denotes uncertainty (which actually can mean honesty: the person wants to be sure of what they're saying and think about it first), confusion, thinking of how to tell the truth but leave out irrelevant or traumatizing information, not being a native speaker of the language one is using, being drunk or high or under medication or sleepy, being absolutely terrified, and more. Because of all of these other meanings, while some liars do hesitate, it's not, in and of itself, a valid way to spot a liar and is worse than useless against compulsive liars, sociopaths, and someone who believes their own lies. This doesn't stop people from believing it is, though, per The Coconut Effect.
Heteronormative Crusader: In the nonviolent sense, Moral Guardians and some political organizations. In the violent sense, gay-bashers and people that attack transgendered people claiming "gay panic."
Het Is Ew: Some types of the Yaoi Fan and Yuri Fan are like this. In a more serious sense, the view of some LGBTQIA people that live in societies that have strict gender roles and rules and heavy stereotyping accepted - they don't wish to emulate the heterosexual roles and find, for example, the idea of alpha males and alpha females playing out sitcom and romance drama stereotypes being the "ideal" to be something people should mature from, not aspire to. And yes, there are the very rare reverse bigots who think heterosexuality is itself gross or offensive.
He Who Fights Monsters: Sadly, one of the most universal truths there is - those who choose violence to stop violence or choose unethical tactics to fight unethical tactics, or similar, even though it may be the only way to stop the existing situation, almost always eventually become the same thing as they defeated.
Hidden Depths: Some people really are more rounded than they may seem at first. Is very, very common with musicians and others who are pigeonholed to a specific "genre" or "scene."
Hiding Behind The Language Barrier: Done all the time, occasionally to insult or mock someone without them knowing. Many English speakers do this as a matter of course, not even realizing they are doing it to any non-English speaker, while at the same time becoming upset if someone is obviously doing it to them in Japanese or Spanish for example.
High-Class Call Girl: They exist, although it's a fantasy stereotype of sex work for the most part, as in most sex workers aren't rich and upper class, and many are the Sex Slave.
Hint Dropping: One of the biggest causes of miscommunication and misunderstanding in the world, because some people don't even get the hint is being made, others get the wrong hint (e.g. someone's trying to hint how much they hate someone, and the person getting the hints assumes that the person is trying to use PUA seduction tactics), or the recipient of the hints wants to be told directly to confirm.
Historical Hero Upgrade: Historical revisionism and needing to make someone "better" than they were for a portrayal. Sometimes the result of the actual truth of someone being found out.
Historical Villain Upgrade: Biased rumors, historical revisionism, and needing to depict someone as "worse" than they were can lead to this.
Hoist by His Own Petard: Happens, because people who hurt other people become or are stupid, overly self-assured, or greedy.
Holier Than Thou: Everyone has met or heard of someone who was a total jerk or hypocrite about religion. This is true for both theistic and atheistic beliefs.
The "Hollywood X" Tropes. Most of them have a germ of truth somewhere in them. The inaccuracy lies in taking a narrow definition and assuming that it's universal.
Home Sweet Home: Nesting instinct in most people kicks in around the late 20s to early 30s.
Homosexual Reproduction: Can happen with a gay or lesbian couple if one partner is transgender and still has the needed anatomy (e.g. a transman who has a uterus and functional ovaries, a transwoman who has functional testicles and penis)
Hope Is Scary: Why some people don't leave abusive or punitive or horrible situations, even if they could and have the wherwithal to do so - to envision a future without the abusive spouse/high demand coercive religious group/bad friend/etcetera is scarier than to know the certainty of the future even if the only certainty is more abuse.
Hope Spot: Sadly, it's quite common in life to think you have a chance at something other than failure or death, for example, and then find out you had no chance at all or you somehow made a bad decision that turned your chance into this.
Horror Doesn't Settle for Simple Tuesday: Killers, rapists, and robbers who work on holidays or significant dates, either out of some personal connection to the day (e.g. Nazi sympathizers acting out on Hitler's birthday) or because it provides far more opportunities.
Hopeless War: They have happened. They are happening. They are perhaps the saddest example of the Sunk Cost Fallacy: the more money, lives, and time poured into a war, no one is willing to admit that it was all for naught and it's time to give up. Hence, the Hopeless War is created and drags on and on with no end.
Hot-Blooded: Some people are this. Alcohol, amphetamine drugs, and/or cocaine can induce it even in those who aren't and worsen it in those who are.
Hot Guy, Ugly Wife: This happens when some guys care about a girl with personality, ignoring how she looks.
House Husband: In places and relationships with more gender equality (or in cases where the woman is rich or has the better career somehow even if it's not an equal society, (e.g. she's a nurse or teacher who's pretty much guaranteed work, the man is a Starving Artist or day laborer or such) this happens sometimes.
Human Aliens: For humans to be able to survive on a planet without terraforming or protective technology the planet needs to have the correct conditions for humans to have evolved there. Some scientists believe that this means that if we find any human-inhabitable words there will probably be aliens there that look just like us!
Humanity Is Infectious: Not with robots, but with some AI programs, which can be trained to post and appear as human beings.
Human Popsicle: Cryonics companies such as Alcor and the Cryonics Institute offer to preserve your whole body or your brain (currently done by keeping the whole head) at low temperatures just after you're legally dead until someone finds out how to cure whatever was killing you. Research shows this might work someday, as the method they use now allows us to freeze and thaw small organs. They'll also have to cure the effects of freezing on the brain, which is somewhat more complicated. Oh, and figure out how to make new bodies for the heads-only crowd.
Humans Are Diplomats: Once some humans learned the value of peace over war, and generally a common trait among more ethical people, who would rather resort to other solutions for anything than violence.
Humans Are the Real Monsters: Face it, we are. Humans are the only species that entirely and willingly destroys the entire ecosystem that supports them for short term gain or profit, and humans are also one of the most violent and most effectively violent internal combat and predatory species in the world.
Note however that other species can also be horrible toward each other (especially paracites and pathogens), even within their own species. It may be that humans aren't inherently more destructive or less moral than other creatures, they've simply had more opportunity to indulge their darker urges by being on top of the food chain.
Humans Are Warriors: Humans are violent predators (though this tendency is beginning to be repressed better and eradicated in some over time) and have often preferred violent or abusive solutions to peaceful ones.
Humiliation Conga: A criminal once tried to trick someone into sending him an Apple PowerBook G4 he bought at eBay. He ended up receiving a binder with keys glued on the inside covers. Read the full story here!
I Ate WHAT?: Understanding what is actually in your food can lead to this - and to becoming a very picky raw vegan if you have the money to be.
I Call Her "Vera": People tend to name (and sometimes gender) inanimate objects. Musical instruments, vehicles, and weapons attract this a lot.
I Call Him "Mister Happy": There are so many euphemistic names for the penis, even excluding what individual men might name theirs, that listing them would not only be NSFW but take up an entire page (and such pages exist elsewhere)
I Can't Believe a Guy Like You Would Notice Me: Because of how stereotyped and restricted to everything from appearance to class to everything else relationships are based on in many societies, and with the constant drumbeat of "you're never good enough" directed at women and at the gay or bi men who buy into it (often younger twinks), this happens when someone is seriously approached by someone that they believe they shouldn't ever deserve.
I Coulda Been a Contender: Bill Butterfield was so bitter about his football career ending in high school that he tried to push his son into athletic success. The results weren't pretty. Also mothers of beauty pageant girls, and parents trying to push kids into careers or better academic levels.
Idiot Ball: Some situations tend to be this because of all of the emotional involvements and fallacies they invoke, making critical and intelligent thinking nigh-impossible.
Idle Rich: Because for some, being rich is their life's accomplishment. Aversions, however, do exist.
If I Can't Have You: Real domestic abusers (especially) and stalkers do act like this - to the point that people who are victims of domestic abuse are advised to make sure their abuser does not know of their escape plans or date.
If Its You Its OK: Because sexuality is a complicated thing, bisexuality is not always a 50/50 split, and it's possible for someone who thinks they are a 0 on the Kinsey Scale (absolutely heterosexual) to meet one person of the same gender that they find absolutely irresistible, and possible for someone who thinks they are a 6 (absolutely homosexual) to meet someone of the opposite gender that they find absolutely irresistible.
If You're So Evil, Eat This Kitten: Asking people to commit crimes or hurt other people or animals or do something else "evil" is a test for everything from criminal groups afraid of police infiltration to some high demand coercive organizations doing recruitment or promotion. A common trick is to hold the person's doing such an act over them as blackmail - e.g. once someone has smoked crack with the dealers and made a sale, they're in as a co-conspirator and capable of being ratted on...
Ignored Epiphany: Admit it, there's been times you've probably wanted to change everything about your life or felt awful about something (whether it be an addiction or how you damage the environment or whatever) and... gone right on ahead doing it while brushing the guilt off.
I Hate Past Me: Everyone at one point or another has looked back on their life and asked at different points "What was I thinking?!".
I Have No Son: It's very common for parents to disown their child, especially when the child is a spendthrift, a sociopath, a substance abuser or criminal, staining the family name and reputation, or even going against their religious beliefs.
I Have to Wash My Hair: Bad excuses are often the best - especially if the date or event is itself not worthy of a good excuse.
I'm Not Here to Make Friends: Became a trope from reality TV, but happens everywhere, especially in business and with people with No Social Skills or interest in staying. Rarely, these people succeed. More often, they fail badly because everyone either hates or doesn't notice them.
Impersonating an Officer: This is very much illegal in every jurisdiction on the planet, but that doesn't stop it from happening.
Impoverished Patrician: Because fortunes rise and fall for various reasons, and especially for those who are rich solely by the actions of others such as family, anything from being disowned to the family funds being lost can cause this.
Improbable Food Budget: Sometimes people do win free food, or know people who work in expensive clubs/restaurants/etcetera and "help out" their friends. Also can be induced by employee theft or shoplifting.
Incredibly Obvious Bug: Surveillance cameras and some listening equipment is this by design, as a deterrent. Chats or other areas online where you are notified that you are being logged or screencapped are the same thing - an attempt to prevent abuse and bad behavior.
Induced Hypochondria: Dr. Google is often to blame, along with its accomplice, Dr. WebMD. Spend time reading around either and you will believe yourself to be ill, possibly dying.
Industrial Ghetto: Because not many people capable of not living in overly industrialized areas tend to choose living there. Hence, industrial areas become restricted to industry and to those too poor to live elsewhere.
Ineffectual Death Threats: Admit it, you've made these. It's also a good idea to be very wary of making them, even in jest, after The Noughties in the US, due to post-9-11 terrorism paranoia, because they can lead to your arrest.
I Never Said It Was Poison: Real criminals actually do this, and it's why police don't release all details of crimes to the media. It is also why if you are innocent and being investigated anyway, you do not try to offer speculation or guesses on who did it, how it happened, or anything else related to it, because if you hit on something by accident, you're likely getting arrested for the crime rather than thanked for your help and let go. If you really want to help an investigation or offer your speculations, especially after having been approached by the police and questioned, only do so via a lawyer or, somewhat riskier, via an anonymous tip.
Infinity+1 Sword: Nuclear weapons, at least from The Sixties until The New Tens. First, you need a lot of highly educated scientists who are willing to create them. Then you need the laboratory facilities and parts and, of course, a supply of highly enriched uranium at the very least. Then you need a delivery system strong enough to deliver them at range without vulnerability to defenses. Then you need a major nuclear-armed nation to back your entry into the nuclear club (usually a member of NATO, though the Warsaw Pact was good enough until The Great Politics Mess-Up) and a convincing cause for why you need nuclear deterrence and aren't just going to nuke anyone for looking at you funny, so the existing members of the nuclear club don't see your nation as a "rogue state" and attack you or sanction you or both. Then, whether you are one of those major nations or a newbie to the club, you have to secure both your peacetime and military nuclear facilities and keep them secure. You also have to develop a strong warning system that informs you on when someone else has launched against you, and maintain intelligence on all other nuclear-armed nations or ally with them. Then there's the physical maintenance of the weapons and facilities themselves...
Infraction Distraction: Often done by criminals and others on the wrong side of the law or the system which they are in - for two reasons, to look "innocent but not too innocent," and to provide something lesser to be charged with if they are caught.
Innocent Fanservice Girl: Show any person over the age of, say, 50 a picture of a random high school in America, and they'll likely insist this is what's going on. Also, the prevalence of Girls Gone Wild videos also leads one to think that the average drunken party coed may teeter into this area after 3-4 shots.
Innocent Bigot: Usually happens with kids, who don't know any better when they first assume their parents/caretakers' bigoted attitudes. Also can happen with the very sheltered, e.g. those raised in restrictive religious systems or isolated locales.
Innocently Insensitive: Asperger's Syndrome, social isolation in general, and being a Fish out of Water can all cause this. Also can happen with people who aren't necessarily familiar with how a culture or subculture operates and what is and is not considered offensive/rude/racist/etcetera.
Inspector Javert: While it's probably not a good idea to list the Real Life examples, they have existed. Prosecuting attorneys are even more notorious for it than police officers.
Inspector Lestrade: This is what happens when cops are Kicked Upstairs. Not necessarily to the degree it is in fiction, but to the degree that many cases are closed too soon, investigated improperly, or otherwise handled in ways that get no one "justice."
Instant Death Bullet: Any bullet or other projectile that hits the brain, a large portion of the time, especially if major brain damage has resulted. Bullets that pierce the heart and lung at the same time or cause major damage to the abdominal organs are also often this trope.
Instant Emergency Response: Happens sometimes out of luck - there is a fire station nearby, or there is a police officer or paramedic or emergency medicine doctor where an emergency is happening. That said, don't rely on it because the only time it happens is via being in the right place at the wrong time.
Insufferable Genius: Architect Frank Lloyd Wright, engineer Isambard Kingdom Brunel, and millions more.
Intelligence Equals Isolation: In communities where women or men (or both) are expected to be "dumb," those who are intelligent are often written off as unfeminine or unmanly.
In the Blood: Sometimes true in that some mental disorders that can lead to violent or "evil" actions are heritable (e.g. psychopathy possibly being one of such), that severe abuse and neglect and an environment Harmful to Minors can do the same, and that the combination of the two is almost always going to cause bad results (e.g. just look at how many pedophiles and serial killers were victims of child sexual abuse from a parent or relative, which indicates both.) Averted, though, almost as often with people who have equally horrible backgrounds and/or disorders, and who don't sexually abuse children or kill anyone.
Intrepid Reporter: Not as common after The Nineties (though a few examples around the world do exist). Press consolidation, the desire for infotainment media, press clubs being about accepting press releases and official statements, the virtual collapse of the newspaper and magazine and TV news businesses, and more, led to this trope being very rare. Citizen journalism, however, via twitter and similar services, has began to somewhat reconstruct it - as have a few news outlets that are nonprofit and/or otherwise not having to worry about keeping the advertisers and Big Brother for a specific nation (except possibly their own) happy.
In-Universe Camera: Just look at YouTube videos of any disaster after around 2000. From 9-11 to 3-11, you will see any disaster from the inside.
It Gets Easier: Militaries try to invoke this in kill training (specifically the US military but others do it too) - to try to get soldiers comfortable with the concept of killing. In general, often does happen with criminal activity, because once one knows how to shoplift or successfully complete a drug deal, for example, much of the nervousness and fear goes away - which actually can be a problem for criminals because once that goes away, they sometimes become Stupid Crooks.
I Thought That Was: Back in the days of video rental stores, porn would sometimes end up in far more innocent cases or sections (e.g. someone would accidentally return a porno in a box for a PG or PG-13 film, or someone unfamiliar with anime would file hardcore hentai under children's animation). This was the result.
It Makes Sense in Context: A lot of things in life are this - context is very important and the difference between many things.
It Never Gets Any Easier: Because some people remain empathetic and understanding of the gravity of injury and death and loss, even if they do have to deal with or have even caused it. Very common among doctors and people in the helping professions and firefighters, and among some police officers that view policing as social work rather than us versus them.
It Only Works Once: Condoms, and disposable items in general (in the sense that they are single-use products). Anything involving the exploitation of anything from a legal loophole software bug that will likely be patched on discovery (in the other sense of something never working again).
It's All About Me: Narcissists and sociopaths on the more extreme end, individual survival and forgetfulness on the more benign.
It's a Small Net After All: In Mexico, everybody uses MSN Hotmail, MSN Spaces, and MSN Messenger, thanks to an alliance between Microsoft and Telmex, the latter a nigh-monopolic telco led by Carlos Slim, the richest man in the world.
It's for a Book: People have used this as an excuse, making things much, much harder for actual journalists or creative writers who are writing a book.
It's Probably Nothing: If you ever find yourself saying this, do whatever it takes to make sure it's nothing.
It's Raining Salesmen: Sometimes they do this to people coming in with bags (or in cases with far more Unfortunate Implications, because you're poor or a minority, because they want to make sure you're not a shoplifter). Also can happen if the sales staff needs to look busy.
It Was a Gift: In some cultures, gifts are considered to have more value because they were given.
