A grenade is a cockblocker who is hating on a player. Grenade usually is addressed as being female. A female who is a cockblocker hating on a player. A player hatress
the woman may choose to be a grenade for various reasons. Typically a girl who is unhappy and would destroy chances of her friends getting laid. I have experienced some grenade cockblockers desroy possible chances of getting laid because they couldn't get any play and they wanted everyone else not to also. this type could be a good sport and let everyone else get laid however when and if they are fat and unhealthy they cannot do the right thing by not destroying everyone elses chances. I suggest you find a wingman to cover the grenade. a wingman like a man saving his troop from blowing up may cover the grenade by keeping her distracted while the players can spit their game so they can get what they want from the other women.

Sometimes you toss it. Sometimes you jump on it. Sometimes you watch it blow.

Jersey Shore Term. The ugly friend that tags along with a smokin' hot chick. In a way she explodes and that affects the friend she's with so she's also a cock block. Really ruins the mood. Makes you feel like you're being closely observed by a gay friend. She can also be the wing-girl. Just in case there's a double-team comin' along.
My friend ended up gettin with a hot chick, while I was stuck with the Grenade.
