When one, or more grotesque women go to a bar, and/or club, and when they cause the people around them to scatter into different directions with their repulsive appearances.
There was a lot of people on the dance floor until that grenade blast cleared the place out.
1)Any extremely attractive girl who surrounds herself by fat, unattractive bitches who usually have way more self confidence than their massive, cellulite filled bodies allow for (see Swamp Donkey)
2)A bottom tier sorority that is constantly launching grenades into your fraternity parties drinking all your alcohol.
1)Damn Kelly is so fucking hot but she is such a grenade launcher, all of her friends are at least 250 pounds and the face of a ferret.
2)Fucking Sigma Kappa, always grenade launching their freshman into our parties!
The sight of spotting a ugly girl in a group full of hotties the grenade is the one who get's no attention from the guys
Group of guys are in the club and spot four hot girls walking threw the door but notice a fifth chick with them one of the guys points at the girl and says look Grenade Alert
