To cup your hand gingerly beneath your arse, flatulate into it, and throw the ensuing stench into an unsuspecting friend's face.
I hand-grenaded him all throughout high school. The gases burned right through his olfactory nerves... poor lad hasn't been able to smell things for years...

The Ugly friend of the Hot Chick that you want to hook up with. Someone has to "jump on the hand grenade" so the other can get to the hottie.

When a guy hasn't jacked off in a really long time, so he has two "hand grenades" in his pants. He uses his hand to 'pull the pin,' and the Hand Grenades explode, ejecting 'shrapnel.'
Dude, I didn't jack off for like a week, and when I pulled the pin last night, my Hand Grenades EXPLODED!!!!!

When a session of fingering your girl starts to get a little dull, let it all end with a bang. Slip your fist inside of her vag, and without warning, extend all of your fingers as far as they can reach. The expression on her face should resemble some sort of surprise.
It was a rather uneventful night until I busted out my ammunition and let that bitch have a hand grenade.
When I saw the slightest hint of boredom in her eyes, I busted out a hand grenade that would have had the vietcong shaking in their boots.
