That kid in your class who thinks he's better than everyone else because he is in a fraternity. The dude wears New Balance because he has to show other people that he is white AF. Frat boys drink shitty beer, tries hard to get laid every night, and wears Vineyard Vines because they think it's cool.
"Dude, your turning into a frat boy, why the hell did you get New Balances?"

Get the Frat boy mug.
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

Wears sorority Crush-event shirts or school polos, chubbies or lululemon athletica and drives around with other frat boys in the back of his truck. Drinks cheap beer and pretends not to know he’s a stereotype.
Chris Reflogal is such a BU frat boy.

Spoiled retards that really just need an excuse to get drunk and party. I'm not even finished with high school and i know how fucking stupid these guys are. Apparently, anyone who doesn't join their "brotherhood" is labeled as lame , gay or Gdi. Despite frat boys are well known to pull "pranks" such as sticking their ass in the face of a nearby sleeping frat , farting then posting it on the internet, just one of the many creepy and gay acts of Frat boys. When they aren't doing this, they're banging useless Sorority whores, date raping , lowering their practically non existing intelligence with beer or simply partying. They tend to believe that because their mommy and daddy bought them through everything this makes them special or cool though 99% still end up flipping burgers at 40, it's recommended not to disagree or even have a different point of view than frat boys. If you do, you're obviously either a virgin or simply just a gdi(even if you're not in college). These are common insults when frat boys realize they are sugar coated turds. If you thumbs this down, you know i'm talking about you.
I don't have an issue with partying and having fun at all, like anyone else i do it too, i also know that not everyone who goes to a Fraternity is a Frat boy. Frat boys however are really just a bunch of spoiled dumb fucks trying to be cool and trying to impress their "friends" they bought for $50 a week.

Someone just nuke the Fraternity please, the street is covered in puke and semen again.

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
2) sleeveless t-shirts
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).
