When a group of guys go to mack on a group of girls, the guy who jumps on the grenade is the guy who goes after the fat chick in the group to clear the way for his friends to go after the hot ones. Usually guys take turns

A term used when a wingman takes the ugly girl interested in you, leaving you open to swoop in for her more attractive friend.
Me: Her friend is so hot, but the ugly girl is into me
Wingman: I'll take her off your hands so you can try the hot girl
Me: Thanks for jumping on the grenade, man. I owe you.

Similar to jumping the grenade whereby your wing man distracts the unattractive friend so you can hit on the attractive one, only in this case the unattractive friend is severely mentally and/or physically handicapped.
His wing man, valiantly jumping the plasma grenade, endured drool and stiff upper limbs so that he could chat up her caregiver.

A female in a group or in a pair, that's not attractive. The one no one wants. But since she's not attractive and doesn't get the same attention as her hotter friends she gets jealous and turns into a cock block.

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.
