A really mean term used by the cast of "
Jersey Shore". Jersey Shore has a cast that are narcissistic, bitchy, "full of themselves", aren't even good looking people, who probably has sex with hundreds of women and men (
yes I'm talking about all eight of them), and aren't educated.
A grenade is an ugly girl who hangs around a bunch of other girls.... some of the "
grenades" they mention aren't even that bad looking.
This term is the reason why girls and even guys have suck low self esteem and result to suicide or depression
