Jump on a grenade 

The generous act of flirting or even dating a certain individual to distract them from, and possibly loose interest in a different individual (usually a friend).

Guy 1: hey man, I need to ask you a favor. I think Nicole is hitting on me.

Guy 2: need me to jump on a grenade?
Guy 1: I mean if you could that would be great. I don't wanna date someone who smells like celery, and I don't want to explain why.

Guy 2: I got you man.

Double hand grenade 

When you put a fist in a girls ass and vagina. You then spread out your fingers while inside of her and make an explosion noise. While making the explosion noise you pull your hands out as quickly as possible.

I gave that bitch a double hand grenade then dropped her off at the hospital. The doctor said that she won't walk correctly for weeks.
