Obnoxious partying males who are often seen at college parties. When they aren't making an ass of themselves they usually just stand around holding a red plastic cup waiting for something exciting to happen so they can scream something that demonstrates how much they enjoy partying. Nearly everyone in a fraternity is a Sorooshbag. And ALL Sorooshbags are in fraternities.
"Dude, I met this total bro the other day,"
"Yeah I think the word you're looking for is Sorooshbag"
"Exactly man!"
"Yeah I think the word you're looking for is Sorooshbag"
"Exactly man!"
