to pull off a Karen

Peeing on a bed that does not belong to you, and make up a ridiculous excuse for it later on.

Oh my god man, she totally pulled off a Karen last night!
-Oh so that's the fish smell!
Haha she told me that she was still wet from the storm, what a lame excuse!
-Next time I crash at her place, I'm going to pull off a Karen everywhere! The couch, the matress. Hell maybe even the kitchen stove!
