jump the grenade

An action performed by the wing man, this situation arises when the said wing man takes one for the team by hitting on the fat/ugly chick in order to help his buddy/buddies score with her hot friends, and therefore, sacrifices himself by jumping onto the grenade. The pin is said to be removed from the grenade when one man goes in alone, and the grenade prevents further interaction with the hot chick(s). Therefore, the jumping of the grenade must be performed immediately before all soldiers are blown to smithereens.
