Cryzombating
Simply put, it's the combination of crysturbating and zombating. It is the act of masturbating in a public restroom, making moaning noises as if you were a zombie, but your also crying while doing this, due to being very upset about something.
That gross bastard Brandon took things to a whole new level after he got dumped by his gf. I found him cryzombating in the Wal-Mart bathroom!
