See Muffler

Suffering the indignity of having your ass kicked and then being stuffed under your own car. Typically done by one's own friends as a result of their cockiness, selfishness and/or rudeness. Once stuffed, the stuffee understands it was deserved and no retribution is allowed.

It was a total dick move showing up to your littles sister's birthday drunk. I've been a real asshole lately. I really need to see muffler.
