A male who spends his time in college trying to party and hook up. They’re probably named something like Chad Brad Chip Casey Brett or something like that. You can usually find them wearing those fruity game day polos, chubbies, Adidas Ultra Boosts, grey sweats, lululemon, Patagonia, or Vineyard Vines. Unless they’re from a black sorority they’re always white or even worse white washed. They usually don’t from wealthy families from the suburbs, and are racist and sexist. They’re also lowkey gay or borderline as most of them do some sus shit.
Frat Boy: Yooooo we’re alpha alpha phi and we’re top house.
Most people: STFU and stop drugging girls

Get the Frat Boy mug.
1.) See homosexual
2.) The same neanderthalistic douchebags that used to play high school football and talk about how shitty you were in high school who now joined a homoerotic club so they can rape each other's ass in private.
3.) A collection of date-rapists that like to drink shitty beer and "stick it in" passed out drunk girls.
4.) Scum of the earth.
5.) A collection of the people with the smallest penises on a college campus.
Woah, look at that frat boy riding around in his giant monster truck with KC lights and the passed out girl in the passenger seat. I hope his truck tires blow out and he flips over and burns in a firey inferno.

A college kid who thinks he's better than everyone else because he is in a fraternity. Some college kids are frat boys even though they aren't in a fraternity. Frat boy behaviour is typified by drinking shitty beer, hitting on high school girls, making fun of punks, and wearing boring clothes.
Dude, these fucking frat boys came to the show at Bernie's the other night, and they started some shit, but my dudes and I kicked their bitch asses.

any college age, needle-dick, weed-smoking asshole who attends college only to party and flunk out. may use roofies to rape women, and finds destroying the property of others an enjoyable passtime. recognizable by

1) caucasian ethinicity

3) inane, misogynistic babble
4) the ginormous SUVs (usually F-150s or Suburbans) with jacked-up wheels they drive, especially with stereos blaring rap or metal
5) visors, especially if worn upside-down, backwards, or a savory combination of the two
6) excessive use of the word "faggot"
7) possession of 40 oz beers, cigarettes, marijuana, and/or beer kegs (full-size or pony). especially alcohol stolen from the local grocery store (see beer run).
