Grenade (n.)

Probably the most ubiquitous term popularized by Jersey Shore, a grenade is a “bigger, ugly chick” who is friends with a cute girl the speaker would like to “creep” on. Compare: “landmine,” a skinny version of a grenade, and “bomb,” a girl that is not interested in your advances and is not afraid to tell you so. Usually, one man in a group will be required to “fall on the grenade” so that his friends will have the chance to talk to her friends. The implications of casting women as various kinds of explosives are as yet unknown for our culture at large, but they’re probably not very good.
