fall on the grenade 

a gent & his mates go to a mixed bar. A group of ladies flirt with them, but unfortunately one of the ladies is VERY ugly (for example, see whalefuck or sealfuck). She is "the grenade". Now, the chicks likely have a deal amongst themselves, if one isn't getting fucked, then they are all abstaining. It is the duty of one of the gents to "fall on the grenade" , that is, to fuck this dog of a coyote ugly chick

One Saturday night I fell on the grenade for my buddies and it turned out to be the hottest fuck I'd ever had. But I didn't want to ever be seen with her again.

Mexican Hand Grenade 

When you take a dump into a sock and then throw the sock at a person like a grenade. Usually done after consuming lots of spicy food. Not to be confused with the Mexican Mortar.

Monty ate a lot of Taco Bell today so he decided it was an opportune time to throw a Mexican Hand Grenade at Shane.
