Friend: Jon have you been working out? Your ass looks ridiculous Jon: Nope I turned my apron into an ass cape. I've already been laid 6 times in the last 9 minutes
When you back out of a terrible situation using your ass as either a literal or metaphorical exit strategy. Can involve physically reversing away from danger, using thicc energy as a social shield, or dropping something so embarrassing that everyone forgets what they were mad about in the first place.
As the great philosopher kenny420g once said: "The ass is a place of escape so it's all the same."
"My boss caught me on Reddit during the meeting, so I pulled an AssCape—knocked my chair over backing up, caused a whole scene, and everyone forgot I wasn't working."
