A large posse or group of wreckless metrosexuals or jocks. Caisoons are generally found in college pubs and bars looking to prove their maculinity by consuming copius amounts of liquor and narcotics. Caisoons are prone to losing in fist fights and will almost always plot a fruitless revenge at the local fast food establishment afterwards.
"It was one of those guys in that caisoon over there that spilled his drink on me last time. Thats why he has that black eye"
