AIDS Grenade (noun): When you start hanging out with a chick who has AIDS, just so that everyone will think you close, and then when your enemies come out of the woodwork to bang her, they get AIDS.
Dude: 'Does Jim really bang that junkie chick who's always hanging around?'

Bro: 'Naw, she's an AIDS Grenade.'

Get the Rusty Grenademug. A one night stand that you meet using the website Plenty of Fish (POF). The origin of this term comes from the similarities between the sound of a smoke-grenade (poffff) and the acronym POF. Also, a one night stand is expected to clear out in a relatively short amount of time, much like a smoke-grenade.
"Hey bro, what are you doing tonight?"
"Not much man. I'm about to go meet up with this smoke-grenade I've been talking too."
"Not much man. I'm about to go meet up with this smoke-grenade I've been talking too."

Get the smoke-grenademug. THE GRENADE THEORY:
1. Throwing an object at someone else for no reason is 'dread'.
2. 'Grenading' someone for no reason is perfectly acceptable.
3. Once 'Grenaded', the victim cannot retaliate unless to 'Grenade' them back.
Got that?
HOW TO GRENADE SOMEONE:
1. Choose your object. It can be anything EXCEPT a grenade. Obviously.
2. Throw your object at your victim, whilst shouting "Grenade!"
3. Duck.
Please note that step 3 is important. Many people do not duck after 'Grenading' someone, making the 'Grenading' void, and meaning the victim can retaliate.
