jump grenade

Acting as a wingman. The phrase comes from the military; jumping on top of an active grenade will kill you but save your comrades around you as a result of it. It's a selfless act for your buddy.

Hey check out those two chicks sitting at the bar. It's a shame only one of them looks decent. Man, will you please jump grenade for me? I did it for you last time.

Jump the Grenade

The act of hooking up with the Fat and or Ugly Girl who is going to tell her hot friend she can't hook up with your buddy. You know, that one nasty chick who is all bitchy right up to the time she realizes she is actually gonna get laid, then she is suddenly cool.

"Buddy, will you jump the grenade and start giving that nasty chick some attention before she claims she has to go home?" "Yeah but if I have to stick in her butt again I'm gonna be pissed"!!!
