The phenomenon of too many dudes hanging out at a social gathering, especially one in which alcohol is consumed in large quantities, without the presense of any chicks; drunk dudes at a sausagefest who start to blurr the lines between just being a "bro" and taking it a borderline homosexual level that starts to get weird
Mark: Dude, were you at Joe's party last weekend?

Neil: Yeah man. It was just Joe and all his weird friends from high school. They were starting to get a little bromiscuous man.

Mark: Like what?

Neil: It started out with some beer pong victory dance they were doing... and then Garrett licked Joe's nipple

Mark: ... thats pretty bromiscuous
