ego-bending

1. An insult/comeback that can humiliate the most big-headed dumb asses.

2. An action or statement that utterly embarrasses the doer or sayer.

1. Prometheus: You are to me as a swarm of ants to a pubic mound!

Bob: Touche! That was ego-bending...

2. In biology: "Masticate?! Are you serious?! HAHAHA!"
