Someone who, like a good soldier, will hop on a "grenade" (ugly girl) and take all necessary damage from said decision to ensure a buddy can score with said grenade's much more attractive friend.

SIDE NOTE: Bonus points if you get a BJ and her name is dyke-ish, like Becky or Barbara but goes by Barbie or something much sexier.
JJ: Look at that blonde over there.
Adam: Yeah, but her friend is fugly.
JJ: You owe me man.
Adam: Dammit, I'll be the Grenader.

Get the Grenader mug.
The real name for the Call of Duty series. The only people who don't acknowledge this as the series' actual name are the hardcore fans, who protect their sacred game above all else, and are ignorant to reason.
Person 1: "I love Call of Duty!"
Person 2: "Don't you mean Grenade of Grenade? I hate that game."
Person 1: (insert rage-filled rant here)

When you're in the shower and you have to poop—Instead of getting out, you poop in your hand, pull back the shower curtain, and toss it in the toilet.
Dude, I had to shit really bad, but didn't want to get the floor all wet.. So I had a grenading session in the shower.

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

Get the grenade mug.
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
"Hey dude, call up that fat chick you've been banging. Tell her to bring her friends."

"Sure thing bro. I guess you wanna dive on some grenades tonight too, huh?"

Get the grenades mug.
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.
He threw the grenade. There was a shout, an explosion, a scream, and then, silence.

Get the grenade. mug.
This waste of (a vast amount of) skin realized in the 6th grade that she will die alone after welfare and multiple heart attacks. After this harsh realization, she desperately attempted to form friendships with attractive girls for the sole reason of leeching of their hotness. Ten years later, she's managed to hold together her parasitic friendship with these girls. When you and your buddies approach these girls, the grenade's callousness from years of fat jokes kicks into overdrive, and she does everything in her power to keep her "friends" from hooking up. The grenade will most likely have to be jumped on (read: get taken back to her place and spend many long hours trying not to vomit from disgust) by you or one of your buddies (probably whoever gets the short straw).
"She was the grenade" should be an acceptable defense in murder cases.
