Pre-Wank 

A male on Chatroulette who is about to start wanking, but isn't yet in the act.

Signs of a Pre-Wank:

1. No shirt
2. In a dark room
3. Does not show his face
4. Hands on the clothed crotch
5. Above the age of 45

if one of these signs is present, then you have enough reason to press f9 (next) as fast as possible

Mike: PRE-WANK!
Patrick: Hit f9!
