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.
