The solitary ugly girl always found with a group of hotties. If the grenade doesn't get any action, then neither does anyone else.

The ugliest girl in a group of girls that are out. Her friends will not even think of leaving her unless they know she is getting action herself. Therefore, someone in your group of friends sacrifies himself by hooking up with the grenade in order for the rest to have a chance of having sex with the hot girls. More often than not, the grenade jumper gets laid and the rest end up jacking off.

A group of ugly, fat, pale, repulsive, and/or slovenly females.

The term "grenade" was coined by The Situation on MTV's infamous show, The Jersey Shore

A throwable or shootable device that can be used in a multitude of military and police applications. Different types of grenades include fragmentation grenades, which send shrapnel flying in all directions, maiming and killing within a certain radius, flash grenades that blind and disorient targets, smoke grenades, which are used on the ground by troops to communicate with troops who are in the air, according to color. Smoke grenades can also be used to provide concealment during movement. Gas grenades can be used to kill via delivery of poison gases, or they can be used to disperse groups of people through the delivery of "tear gas." Incendiary grenades are typically used to disable enemy equipment, as they usually contain thermite and can go straight through an engine block. Most grenades are either deployed by hand or shot from a hand held or turret mounted launcher.

Hand- held explosive, used mainly by people who wish to inflict pain and death. (eg. Terrorists, soldiers)
To use a grenade, one would remove the pin and throw the grenade in the direction of the target, where under normal circumstances, it would explode.
Not reccomended for children. Or anyone at all, really.
