These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Any politician who's not Ron Paul, Bernie Sanders, or Elizabeth Warren. Especially if they're Republican.
Gawker, which is hated for its political correctness, and often accused of inflammatory tabloid-style clickbait
Tumblr, the Sitcom Arch-Nemesis to Reddit and considered its Evil Twin - its bigger focus on images, the average user being female (and sometimes non-white), and, of course, everything that Reddit is not when it comes to social justice.
For r/shitredditsays, Straight Able-bodied White Cisgengered Males (SAWCASMs). For Straight Able-bodied White Cisgengered Males (SAWCASMs), r/shitredditsays.
r/cringe (and by extension, r/cringepics) loves to make fun of bronies.
Brain Bleach: Needed for r/spacedicks, a Shock Site in the vein of Goatse/Pain Olympics (with a dose of randumb humor.) Mentions of it on other subreddits tend to garner "SWEET JESUS WHY DID I CLICK" responses and requests for Brain Bleach.
There's a subreddit called r/Eyebleach where users post cute and sexual things. "After a long day of seeing what internet anonymity can do to people, you're bound to need some eyebleach."
r/shitredditsays: Straw Feminists with Hair Trigger Tempers or a useful antidote to the rampant misogyny on Reddit? Either way, whenever a post gets featured on SRS, expect a flame war to break out between regular Reddit and SRS in the post itself.
r/mensrights and r/atheism are both very popular but also considered two of the worst subreddits to the point where there are multiple blogs and videos dedicated to bashing them, and the mere mention of them on Reddit (or offsite) will result in a Flame War.
A number of subreddits have split due to in-fighting. Perhaps the most infamous being the migration from r/marijuana to r/trees due to a controversial moderator.
Broken Pedestal: The user u/Unidan, who had built up a reputation as a knowledgeable biologist and becoming one of the most well-known and liked Redditors, was revealed to had been using alternative accounts to upvote all his submissions after he and another user engaged in an argument over the difference between crows and jackdaws.
Browser Narcotic: We're not joking when we say Reddit is more addictive than TV Tropes!
Berserk Button: Comcast, if there is any "worst things ever" it's always mentioned.
<holds up spork>
Discredited Meme: Other communities tend to view Reddit using a meme as causing this.
With 4chan, although it is a bit more one-sided. 4channers are shown to despise Reddit, whereas Reddit seems to admire some of the more intelligent/witty posts that manage to come out of 4chan. (4chan thinks that this is stealing.)
And with Gawker Media. Redditors have always hated Gawker for its alleged pandering to the Lowest Common Denominator, and it only got worse after Violentacrez's doxxing/departure. A few subreddits even banned links to Gawker's sites
Also with Something Awful. Something Awful hates the site for being a haven of what they consider everything wrong with the internet, partially due to some child porn subreddits that have since been purged.
Some SA goons started ShitRedditSays, a documentation and mockery of all things considered wrong with Reddit's very politically incorrect vibe. Both goons and Tumblrites use SRS, and both will be happy to tear apart every vaguely creepy or hateful comment that pops up in the subreddit.
"Funny Aneurysm" Moment: A video of a guy complaining about constantly being rejected was posted to r/cringe just 4 days before said guy later shot 6 people dead. Most of the Redditors in the thread mocked the guy and thought he was too much of a childish idiot to actually harm anyone.
The site has generally gotten a lot of flak since its sudden rise in popularity when Digg changed its layout.
The popular default subreddits are particularly criticized. The common advice is to unsubscribe from those and subscribe to smaller subreddits instead.
Many state that subreddits start to lose quality once they get over 10,000 subscribers.
Know-Nothing Know-It-All: What a certain Imageboard would like to believe its Redditors are. With the extremely casual and accepting fanbase, accounts designed around karma, and discussions sorted by date as well as by likability, Reddit is the antithesis of its competition, which "ironically" uses Rage Comic edits as mockery. The unfortunate result of the karma system is that downvoted comments, even if they have merit, are quickly shoved aside. It's really up to personal preference.
GRANDMA TAKING A SHIT IN THE DARK: From a rage comic where the protagonist goes to the bathroom at night, only to discover his grandmother already using it without the lights on.
It went okay.: From a post where the poster claimed that his female roommate would masturbate daily and that he planned to walk in on her. When he finally did, "it went okay."
Rage comics tend to agree that the best solution to finding a spider in your house is to not be shy with the gasoline and burn your house down.
"No, that's [blank]. You're talking about [phrase].": These are long-running threads about a poster mistaking something for something that sounds similar (the [blank]). The [phrase] will be a description of something else that sounds similar, which the next poster will similarly debunk. Example.
Similarly, if someone makes a pun, a long thread of further punnery is almost guaranteed to happen.
SO BRAVE: Said in response to someone declaring a widely held opinion, such as "Creationists are stupid".
Jolly Ranchers/Doritos/Cumbox: Three infamous Nausea Fuel stories that invite a flood of "OH GOD WHY" comments whenever they're mentioned. Disgusting tales will inevitably be compared to one or all of these.
"Would you rather fight one horse-sized duck or a hundred duck-sized horses?" A traditional AMA question that first appeared in President Obama's AMA (he didn't answer it, but most people wish that he had).
"le lol omg le dis comic" and variants are mockeries of various reddit images and posts ("le" is often used by Reddit in just about everything).
"You have been banned from r/pyongyang" Refers to an incident where posters of r/MURICA! invaded and vandalized the r/pyongyang subreddit with American silliness. r/pyongyang completely shut itself off from public viewing and banned everyone involved. Now anytime a negative statement about North Korea is made on the site, someone will respond like this.
Alternately: "You are now a moderator of r/pyongyang" for positive statements about North Korea.
Narm: An insightful, informative posting can seem jarring when coming from a silly username.
Or it may just be the content of the quote. One now-infamous example reads as the following: "In this moment, I am euphoric. Not because of any phony god’s blessing. But because, I am enlightened by my intelligence."
Never Live It Down: Outside of Reddit, the site's becoming known as a haven for pedophiles and misogynists, to say nothing of its reputation with 4chan and Something Awful as an unfunny ripoff of 4chan memes, shitty internet humor, and an echo chamber for militant atheists and libertarians. And ruining fedoras. Even though the Subreddits responsible for Reddit's reputation (Creepshots, Jailbait, among other things) are now gone, were heavily derided and avoided by the userbase before their deletion, the defense of the subreddits existing as a form of 'free speech' only sealed in Reddit's reputation.
Even as important as having a high karma score is, some users try to get as much negative karma as possible by posting offensive comments.
The SRS mods credit the fempire's growth to bigots ranting about them in other subreddits, and inspiring people to see "just how bad it is".
Political Correctness Gone Mad: What everyone thinks about r/shitredditsays, except r/shitredditsays themselves of course. Not surprising, as it's pretty militant in tone, quick to ban, and happily admits to being a "circlequeef".
Ron the Death Eater: SRS loves to do this to Reddit as a whole, painting all of its (male) userbase as racist, misogynistic pedophiles. The rest of Reddit, in turn, treat all of SRS as evil, humorless, man-hating harpies, which SRS gleefully mocks.
Rule-Abiding Rebel: The "So brave" meme was created to make fun of users that claim to have controversial political and social opinions, but largely conform to acceptable opinions on reddit. "So edgy" is a similar catchphrase in SRS comment threads, with many of the same connotations.
r/jailbait, r/creepshots, and similar/related subreddits. It's a long story. The short version: Reddit's mods were reluctant to remove even subreddits distributing child porn and photos taken without consent because it was "against free speech"; it took media attention and a long campaign by Something Awful and affiliated sites for anything to be done about them.
Gawker Media. Already unpopular with reddit beforehand, Gawker published an expose on violentacrez (the creator of r/jailbait and various other creepy subreddits) that lead to him being fired from his offline job; a number of subreddits subsequently banned links to Gawker.
"Power users" with loads of comments and karma inevitably attract a hatedom, because internet points are Serious Business.
"Novelty accounts" (users who operate on a single gimmick, such as AWildSketchAppeared making a sketch of a comment or ActuallyTwoLlamas posting an image of two llamas instead of a relevant image), when the joke wears thin.
Then you have the people who complain about the people who complain about reposts.
People who complain about people putting punchlines of pictures in the title whether the punchline would actually make sense without the context of the picture have been called this as well.
They complain EVEN if the picture's questioned punchline isn't even the punchline to begin with.
People who complain about memes, or people who complain about using memes "incorrectly".
People who complain about image posts.
Why will you always receive downvotes for a neutral post or comment about something? Nobody knows, because if you try to ask, your comment will be downvoted into oblivion.
Many posters on r/malefashionadvice will simply put down someone asking for an opinion on some even slightly out-there clothing item. There's a reason the sub is derided on the rest of Reddit for promoting a "template" look.
/r/circlebroke and r/negareddit, having a tendency to dislike anything deemed popular on the rest of Reddit. /r/subredditdrama also can dip into this, depending on what group of users are perusing it at the time.
SRS really, really hates any politically incorrect jokes, especially highly-upvoted ones. Jokes about having sex with inanimate objects have been featured on the subreddit.
