Typically used by people to put down college men who belong to a fraternity. While you will find the occasional member who is shady, obnoxious, or in some way fits the stereotype, the majority are intelligent, fun, and good-looking young men who understand the true meaning of brotherhood as friendship and striving to meet the high ideals of their organization. Sometimes, the phrase is used by a sorority girl, and in that case it is usually not derogatory.
"Why are you going out with a frat boy? They're all weird, preppy guys who have low GPAs and don't care about women."
"Stop putting down the Greek system when you obviously know nothing about it."

Members of a fraternity on a given college campus. Usually people who enjoy drinking to excess 3-4 nights a week. Mostly majors of finance, econ, other business. Can party all the time and still get high paying jobs out of college because their parents (or friends parents) will hook them up with employment. Frequently referred to as being "gay" by non-frat members who are jealous because they can't get hot pussy.
Frat boys have parties filled with at least a 60/40 girl to guy ratio and bang hot sorority girls...Non-Frat boys go to sausage fests where they bitch about how gay frats are...then go home drunk and alone to jerk off

The final stage of gay denial. These guys shower together, they slap each other on the ass, they fall asleep next to each other after all night drinking and talking about how much they love each other. But if you happen to be wearing a tie they call you a fag.
Frat boy 1: "Hey let's go play some touch football then shower together and slap each other on the ass."

Frat boy 2: "I'm there dude. Everyone who isn't in a frat is gay."

Frat boy 1: "Shut up and keep sucking."

Frat Boy-A member of a fraternity in which the belief that he is better than the rest of the world is passed on. Because it is true. Frat boys are a group of guys who band together to get drunk faster, or get high faster or do something better than everyone else because after all they are better than everyone else.
I am a frat boy and I am better than the world.

Better than the average human being. A Fratboy is intelligent, social, athletic and successful. GDI's try to act like they are above fraternities but in reality they are still stuck in high school and dress like middle schoolers and guidos. Fratboys get girls, money, and jobs after college. GDI's get their right hand, a job under a fratboy, and their parents basement for a future home. Minorities also tend to hate fratboys because either A) They can't afford to join a fraternity. B) Even if they could they wouldn't get in.
Guy 1:Dude she totally wants you dick!

Guy 2:No shit, I'm a fucking fratboy and she's a total sorostitue.
