Crimson Grenade 

A used tampon which has been removed from a woman's vagina for the purpose of throwing (often as a weapon in a fight).

Becky and Tammy were fighting over some pointless bullshit when Tammy reached into her Spanx and pulled out a drippy Crimson Grenade. She flung it at Becky, but it missed and stuck to the wall.

Harvey Hand Grenade 

Invented in Harvey, New Brunswick, Canada. A form of foreplay whereby the fist is inserted into the partner's rectum. Once fully inserted past the wrist one attempts to fully open the hand and extend all digits. When performed solo it is referred to as the Harvey High Five.

Due to an increase in medical expenses the Harvey Hand Grenade is now forbidden in all New Brunswick Prisons.

ass grenade 

A ball or clump of poop capable of being thrown straight from the butt as a grenade.

I went to the zoo and saw two monkeys hurling ass grenades at each other. Then my roommate and I went back to our room and did the same.
