Pulling a Mordecai

Named after the Regular Show character, Mordecai. Used to describe a guy who is too afraid to ask a girl out.

Rigby: Ugh! All you do is text CJ. Just tell her you like her and quit Pulling a Mordecai.

Mordecai: What?! That's not a thing!

Rigby: "I'm Mordecai, I never make a move and I don't know what to do with my hands". You've been doing this for years.
