Defilade

Word used by bitch-ass military personnel during firefights, it is an order to take cover from incoming fire instead of just absorbing the bullets like the rest of us. Also used by dumbass WW2 cosplayers to sound cooler. They usually got it from the movie Saving Private Ryan because their research consists of going on reddit threads and sorting by top. Anyways, it is french-english in origin invented in the 1820’s to 1830’s where they finally grew a brain and thought of not standing directly in the line of fire and get a golf ball sized hole blown through them because humans are essentially a bag of jelly filled with smaller bags of jelly. I have a casino to get to...

Rectal defilade

The state or condition of having something up your ass. Most often used in reference to the location of a stupid person's head.

Origins: The term "defilade" is used in military tactics to refer to a position where natural surroundings protect units, vehicles or equipment from enemy fire.

Sgt. Slaughter: "Private Pile might be the stupidest person in this company. His head is so far in rectal defilade that he can see his own teeth."
