A guy in a group of friends who always falls on the grenade the grenade. A flak jacket provides protection from grenade shrapnel to the wearer in real life, while a figurative flak jacket protects his group of guys from getting grenades. A flak jacket is not to be confused with a wingman a wing man is usually a relationship where all guys are on equal terms and take turns wing-manning for one another, however a flak jacket usually has less game than the other guys so he is almost always willing to take the grenade, because he can't get other girls. A flak jacket is a great friend to have because it can protect you from potentially lethal grenade shrapnel while flirting with chicks.
Friend #1: Hey man look at those three chicks over there, I got the hot blonde with the big tits.

Friend #2: Fine I got the fine latina chick with the awesome ass.

Friend #1: I guess that means you got the pig faced chick man.

Friend #3 (flak jacket): Fine if you say so, I guess Im falling on the grenade again.

The mountain of fat that only obese women have in between their vagina and chin which blocks a man from being able to pull out of said woman and cum on her face
I wanted to finish on her chin but she had a Virginia flak-jacket so I couldn't
