look up any word, like pussy:

This waste of (a vast amount of) skin realized in the 6th grade that she will die alone after welfare and multiple heart attacks. After this harsh realization, she desperately attempted to form friendships with attractive girls for the sole reason of leeching of their hotness. Ten years later, she's managed to hold together her parasitic friendship with these girls. When you and your buddies approach these girls, the grenade's callousness from years of fat jokes kicks into overdrive, and she does everything in her power to keep her "friends" from hooking up. The grenade will most likely have to be jumped on (read: get taken back to her place and spend many long hours trying not to vomit from disgust) by you or one of your buddies (probably whoever gets the short straw).
"She was the grenade" should be an acceptable defense in murder cases.

The grenade is an alternative sexual manuaveur, it begins with the basic handjob. When the man begins to orgasm however is where the grenade differs because the one handjobbing makes a fist around the erect member and clamps their thumb over the penile orfice. This is usually followed by a yelp by the man because of building pressure and is usually released quickly with a explosion of white male secretion.
Me: Hey dude why are grabbing yourself?
Mike: My girl gave me the grenade because I called her Heather half way through.
Me: Shit thats some mean and cold hearted shit right there.
