The Fratbro is a character depicted in a stereotypical fratboy-ish manner. They're almost always not very intelligent and usually want to party and drink all day (and try to get laid) and will likely engage in Wacky Fratboy Hijinx. Despite the name, they don't have to be (or have been) in a fraternity in college.
In a lot of ways this character is an evolution of the Dumb Jock stereotype as they often fulfill the same role, although the Fratbro will not necessarily be an athlete (he will at least be a big follower of sports, however). Also unlike the traditional jock, the Fratbro will often be a very big fan of soft drugs (particularly cannabis), and be portrayed as being pretty much harmless in comedic works, but darker examples will frequently throw in a proclivity towards Date Rape and a tendency (since they are usually from upper-middle-class/upper-class backgrounds) to attempt to use family connections to get them out of trouble.
This is a subtrope of Men Are Uncultured, specifically designed around the idea that it's "normal" for young men to behave this way and sow their depraved "oats" before stepping foot in the real world. The ones who can't let go of this phase in their lives may grow up to be a Jaded Washout or The Stoner.
The Fratbro is usually an Acceptable Target in pretty much any work not aimed at this demographic. Often used as a Bromantic Foil to the male lead. One popular Aesop for this type of character is to become a Ladykiller in Love, especially if they Can't Act Perverted Toward a Love Interest. Whether or not it works is a toss-up, as this sort of character can easily imply that the audience Should Not Do This Cool Thing.
- Stifler in American Pie. Even before he went to college, he fit the stereotype perfectly being a boisterous party animal focused on partying and getting laid. It's rather telling that his Character Development in the sequel is "becoming comfortable enough with his sexuality to kiss a dude in order to have a threesome with lesbians."
- John "Bluto" Blutarsky of Animal House is the Trope Codifier. Frequently drunk, and always on the lookout for mischief, he neglects his studies to the extent of receiving a grade point average of exactly 0.0. His many fratboy activities include starting a cafeteria Food Fight, spying on women students changing and smashing someone's guitar in the middle of a song. When the dean expels him and his frat brothers, Bluto rallies them to commit one last act of mayhem at Homecoming.
- The title character in Van Wilder is a mix between this trope and a Big Man on Campus. Ironically, the film's main antagonist is the actual president of a fraternity but he does not fill this role and is instead portrayed as a Jerk Jock and a (male) Academic Alpha Bitch.
- Teddy Sanders and the rest of his fraternity brothers from Neighbors all fit this stereotype. The film actually serves as a Deconstructive Parody of frat boy comedies, showing the worst aspects of the immaturity displayed by Fratbro characters when surrounded by reasonable people.
- Initially Subverted but later Enforced in The Cabin in the Woods. Curt is introduced as a generally intelligent and sensitive character, but needing him to fit a stereotype, the Controllers begin manipulating him with drugs until he fits this trope perfectly. Forms a plot point as well: it is so out of character that it makes Marty suspicious.
- Web serial Barkwire gives us Clumpy, the stray dog loved by college students (and tragically lost to liver failure).
- One of the entries in Gravity Falls: Journal 3 tells of the Author's encounter with the "Abominable Bro-Man", a Sasquatch who dresses and acts like a stereotypical frat boy.
- In The Mark and the Void, the team of bankers the Caliph of Oran sends to make a deal are all 18-year-olds who are interested only in drinking, drugs, and making lewd jokes. Being English, they all have somewhat ridiculous cockney accents.
- How I Met Your Mother:
- Ted (currently a college professor) "saves" a girl who is being hit on by a pack of these. The leader (dubbed "Boomer" by the girl, the kind of nickname a fratbro would have) tries to convince her to join them to come to a party. Ted confiscates their beer... but not their hard lemonade. The girl even laments that dumb frat guys invite her to a kegger every single week.
- Recurring character Brad is a Genius Ditz version of this. He's first seen hosting a wild college party (though as law students, he made everyone sign a waiver before they could "FREAKING RAGE"), his later appearances that season included a bromance with Marshall, and disappearing during Marshall's bachelor party only to reappear at the end, naked and wandering the streets. He also speaks like a bro, almost to the point of a verbal tic.
- Sam leaps into a Fratbro in an episode of Quantum Leap, and has trouble getting the Girl of the Week to listen to him because she knows him to be a jockish ass. His fratty mates keep appearing and trying to embroil him in wacky high jinks, including raiding the office of "Dean Stockwell".
- In The Office (US), Andy was a former Frat Bro at Cornell and was in an a capella group. He often gives his co-workers silly nick names and even has several of his own ("Nard Dog" being the most common). It seems he was pretty popular at college but not so much in the workplace.
- Troy from Community begins the show somewhere between this and Dumb Jock, having injured himself performing a "keg flip" but he's open to Wacky Fratboy Hijinks. He quickly evolves past this, becoming a much more rounded character.
- Buffy the Vampire Slayer: They show up in the fourth season, when the gang goes to college. A group of them accidentally summon a fear demon while turning their frathouse into a haunted house.
- "Captain Awesome" from Chuck is a somewhat more nuanced, mature version of the fratbro. His mode of speech is very reminiscent of the archetype (including a fondness for the word "awesome" which provides his nickname), but rather than being a shallow party animal, he's a compassionate doctor.
- It helps that he's more Surfer Dude than Bro, and drawing on that archetype has a lot fewer negative associations to begin with.
- Eric & Jeremy from The Amazing Race 9, who even earned themselves the nickname "The Fratboys" despite never having gone to college. They were a couple of slackers who hit on every woman they came across in an overly douchey fashion. Eric would return for All-Stars with a woman he met on Season 9.
Jeremy: We want to win. Whatever it takes to win.Eric: It's like trying to get into girls' pants, y'know, lie, cheat, steal. You know, whatever you can.
- In one episode of It's Always Sunny in Philadelphia, the gang attempts to reclaim their dominance in "Flipadelphia", a local version of the Flip Cup game. With their old bar rivals now refusing to play them, they instead end up challenging a group of fratboys from Dennis' old college fraternity.
- Vernon from You're the Worst still behaves much like an especially immature one of these despite being almost 40 years old - he constantly spews juvenile humor and insists on making highly alcoholic "trash juice" punch for parties. His wife Becca even calls him a "talking penis in a clown wig".
- Dane Cook was often seen by fans and critics alike as an archetypal example of Fratbro comedy, with much of his material focusing on telling long anecdotes about drunken antics and dating/relationship issues. Perhaps unsurprisingly, his fanbase during the peak of his success largely consisted of teens and young adults and he would often perform in college towns during his stand-up tours.
- Cook's spiritual predecessor Andrew "Dice" Clay could be considered an example as well, as he cultivated a macho "guido" image and focused on similar subject matter (drinking, sex, and other debauchery) in his jokes.
- League of Legends: Pictured above is the Champion Olaf in his alternate skin: "Brolaf". Usually, Olaf is a berserk viking Blood Knight who is a Death Seeker and generally rage-filled. Equip the skin, and his personality goes a 180, into an immature dude who likes hot babes, chugging beers, makes Your Mom jokes, and his Battlecry being a parody of an existing meme, being... BROMACIA!!!
- Not to be outdone, Smite also released a skin for He Bo, the God of the Yellow River... into "He Bro", who turns the Chinese sage into a combination of this trope and Surfer Dude.
- Kagura Mutsuki from BlazBlue: Chrono Phantasma has this as his mindset of least resistance - that is to say, give him enough time without inhibitions and he will party with a hot babe (or several) with alcohol for everyone. This usually lasts until Hibiki or Makoto find out - the former will lecture him at great length about not taking his job seriously, while the latter literally beats it into him. That he is introduced suffering from a hangover after a floozy runs out on him doesn't help his case - Noel even points out that the room "reeks of alcohol". His Fratbro personality does not in any way stop him from being a Colonel Badass, however.
- The Frat Orcs of Kingdom of Loathing combine traditional fantasy orcs with this trope and many other frat-boy stereotypes. For example, they drink Swiller beer and use frat paddles as weapons.
- Saints Row: Gat Out of Hell has demon fratbros as one faction of demons for Johnny Gat and Kinzie to contend with during their time in Hell.
- In Questionable Content there is a trio of background bros who appear and chant "BROS!" whenever someone says the word. Between the three of them they demonstrate fratbro-attire quite well, wearing college-labelled clothing, hoodies, and pastel polo shirts. No surprise that they first showed up at a bar.
- Chapter 7 of Volume 1 of Druid City is full of fratbros. Two serve as the antagonists of the chapter, four others serve as charmless rubes, and many others appear as copy-paste versions of themselves in a dance sequence.
- Homestuck has the aptly-named Bro Strider (also known as Dirk Strider in an alternate universe). He outright says that he aspires to be the ultimate "bro". He's obsessed with baseball hats (if he can't wear one, he does the next best thing and wears a t-shirt with a picture of a hat on it), rap music, videogames, unhealthy snack foods, extreme sports, and videogames about extreme sports and unhealthy snack foods. Bro's brother, Dave, copies many of these interests to an extent, but he's doing it "ironically" while Bro's irony is so far gone that it's completely indistinguishable from sincerity.
- VG Cats: Bro Gamers.
- Yahtzee from Zero Punctuation characterizes Xbox 360's target audience as being largely this trope, largely due to the popularity of their multiplayer shooters appealing to them.
- The Derrick Comedy skit "Bro Rape" is about bros being, well, raped by other bros. It's styled like a "To Catch a Predator" segment, luring the predator-bros into police sting operations with an online profile named "Chad" who professes to enjoy bro-related activities such as drinking beer, playing video games, watching TV shows like Family Guy, and getting raped by big black dildos. Incidentally, the sketch also stars a young Donald Glover, who plays the aforementioned Troy in Community.
- A few of Cecil and Kain's lines in the Playstation version's translation of Final Fantasy IV are like this. Legends of Localization refers to this as "Cecil and Kain, who are super-high ranking knights, talk[ing] like college bros or something".
Kain: Hey, 500 Gil says I slay that beast tomorrow.Cecil: Alright, you're on.
- In the early-mid-2000s, many critics classified Tucker Max and, to a lesser extent, Maddox into a new subgenre of humor literature known as "Fratire" after the rise in popularity of their personal websites and subsequent books, which frequently focused on manly subjects such as drinking and partying exploits. Subverted by the fact that neither Max nor Maddox were ever members of fraternities in college and both later criticized the label.
- CollegeHumor: Played with in "If I were a Bro", wherein Sarah dresses up as a stereotypical frat boy hanging out with the rest of the dudes.
- In spite of (or perhaps because of) Family Guy's reputation of being popular with teenage/college males (as exemplified in the page quote), the show has frequently taken potshots at fratboys. In one particular example, Stewie develops a Precocious Crush on his college-aged babysitter but becomes heartbroken when he discovers that she already has a Fratbro-type boyfriend, prompting him to launch into an epic rant that hits on nearly every stereotype of the trope:
Stewie: Ha! I got your hat! Take that, hatless! Now go back to the quad and resume your hackey sac tourney! I'm not gonna lay down for some frat boy bastard with his damn Teva sandals and his Skoal Bandits and his Abercrombie and Fitch long sleeved, open stitched, crew neck Henley smoking his sticky buds out of a soda can while watching his favorite downloaded Simpsons episodes every night! Yes, we all love "Mr. Plow"! Oh, you've got the song memorized, do you? SO DOES EVERYONE ELSE! That is exactly the kind of idiot you see at Taco Bell at 1 in the morning! The guy who just whiffed his way down the bar skank ladder!
- In The Simpsons episode "Homer Goes To College", Homer attempts to cultivate this image when he attends Springfield University to take a course in Nuclear Physics. Unfortunately, he learned all of his stereotypes about college from watching raunchy 80s comedy films and soon learns that real college is nothing like what was depicted in fiction. He eventually befriends a trio of nerds and attempts to teach them how to "par-tay."
- Rocco from Undergrads. He's so prone to Wacky Fratboy Hijinks that he hazes himself when the frat doesn't. He spends the rest of his time drinking and being a perv.
- An episode of South Park portrays musical theatre creators Stephen Sondheim, Stephen Schwartz, Andrew Lloyd Webber and Elton John as all being beer-swilling bros in secret.
- Season 19 features stereotypical frat bros who are all obsessed with enforcing Political Correctness to the extreme, with one of them being the new principal of South Park Elementary.
- In The Grim Adventures of Billy & Mandy, "Attack of the Clowns", while Mandy and Grim are trying to help Billy conquer his fear of clowns, Billy goes to his happy place in his mind where he encounter his imaginary "Inner Frat Boy" who helps Billy conquer his fear by giving him some pretty sound advice, "Just because somebody's different from you doesn't mean you should be afraid of them... It means you should be angry at them."
- Aqua Teen Hunger Force has the "Frat Aliens" (Donkey Puncher and Skeeter), who are aliens that behave like stereotypical fratboys, except From Space. Their very names are lewd sexual terms ("Donkey Punch" means to punch someone in the back of the head during doggystyle coitus, and "Skeet" means to ejaculate on someone).
- Code Monkeys features Dean, the college-aged son of Game-A-Vision's CEO Bob "Big T" Larrity, who fits the stereotype to a T. In one episode when he becomes the acting head of the company, Dean hires several of his college friends, who are members of the Alpha Sigma Sigma fraternity.
- In The Middle Ages, university students were condemned for drunkenness, getting into violent brawls, and engaging in all sorts of mistreatment of women up to and including rape, making this Older Than Print.
- The infamous Bullingdon Club is basically a cross between this trope and a Brotherhood of Funny Hats. They recently got some rather unfavourable media attention after allegations were made that a fratbro who went on to become Prime Minister of Great Britain had to perform an indecent act with the severed head of a pig as part of the Initiation Ceremony.
