Skipping one's classes or other academic obligations for an extended period of time in order to pursue other, more socially rewarding activities, such as drinking, golfing, and deep sea fishing. Other acceptable albeit less fratty activities include sleeping, movie-watching, and playing Call of Duty.
Zach showed up to Intro to Accounting for the first two weeks but then decided to go on fratbatical and wasn't seen until the final exam.
One of those fag-ass frat boys, who live their failed athletic careers through fraternity sports. They usually weren't that good in high school, but seem to do alright in frat sports. Thus, they think they're big men on campus because they hit the game-winning home run, freethrow, etc. although they are playing against many others who are equally as bad or worse. They take away from the real hard work and dedication us REAL collegiate athletes put in.
A sexy boy who is in a fraternity. He's also on an athletic team. No, not a little baby rec-sports one. A real-live sweaty school one. They chant and scream both on and off the court!
Hey girl, where were you last night?
