When you and your friend fuck two different girls in the same room, at the same time. It's all business, no bullshit. You go in piss drunk with two absolute sluts (preferably from a different college) and each horny couple gets on a bed. They all have sweaty loud sex and create a cloud of musty badussy that resembles the smell of cracking open a smelly sardine can. Finally, you pass out naked knowing you might have seen your homies cock and balls. Extra credit is awarded if one of the guys is not your roommate and just obliterated your roommates' sheets with genital fluids. Only a real ass boss is a member of the sardine club.
All the bitches at GW want to be a part of the sardine club.
