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.
