Define Fall On The Grenade Meaning

Hot chicks always hang out in groups. There is always one she-beast in a group of hot chicks. That's the grenade. The grenade's job is to cock block for her hot friends... if the grenade ain't gettin love, the hot chicks ain't either!

the selfless act of working your way into the pants of a fat ugly female troll so that your buddy can get laid by her more-appealing ladyfriend; hopefully he signals his success before you have to actually consumate the deal, you don't want to be waking up in the morning with the coyote ugly troll laying in your bed

To make a sacrifice for the good of others. Originally a military term for when a junior officer would deliberately fall to cover a grenade - the explosion from which would kill a far greater number of his side if he didn't. In particular, it would be when a junior officer would make this sacrifice for a senior one - to protect the commanding officer for the benefit (supposedly) of the army.

Its meaning has been expanded to cover things like taking the blame for a team-fuckup (eg. at work) or humpin a dawg so (as said above) your mates can get into the pretty ones.

being the "wingman"

a gent & his mates go to a mixed bar. A group of ladies flirt with them, but unfortunately one of the ladies is VERY ugly (for example, see whalefuck or sealfuck). She is "the grenade". Now, the chicks likely have a deal amongst themselves, if one isn't getting fucked, then they are all abstaining. It is the duty of one of the gents to "fall on the grenade" , that is, to fuck this dog of a coyote ugly chick

the selfless act of skull fucking a fat troll so that your roommate can get his nob shined by her slightly more appealing friend, only to boot the troll to the curb once you have confirmation that the roommate has "sealed the deal".

To take a hit for the team. To make a sacrifice (implication being a SUPREME one) to save your friends. By extension, to accept the inevitable.

to fuck and ugly she-beast so your friend can fuck the she-beast's hot friend

to occupy the time (read: fuck) an ugly chick so that your friends can fuck her friends

According to Bud Light advertising officials, to fall on the grenade means to choose the more intellectual of the two scantily clad, leggy, voluptious super models cast to play bicurious friends opposite you and your equally unattractive, slightly overweight beer drinking cohort. Forcing you to sit and drink bud light whilst tuning out the dull, empowered, feminist rambling of the prude, abercrombie wearing, never-going-to-fuck-you hottie, while your buddy drinks bud light and dances his way into the looser hottie's panties. The intellectual one is always wearing glasses. Still you have a chance to possibly fuck the prude if you feign interest and agree to every fucking thing she says, but do you want to? Make sure not to drink too much bud light, no matter how long this bitch rambles on. You must be conscious to get the fuck out of there after she falls asleep or you're in for a hellish morning after.
