Shortening of the term Cock Block.
Dude, I was hitting on this chick and he c blocked me by showing off his Mercedes. Now she won't talk to me.

cock blocked...not getting any pussy when you really need it because of unforseen forces beyond your control
I am getting c-blocked from all angles...either my girlfriend gets a phone call or someone comes to her house right when we are ready or I'm on line chatting with some hot babe and my computer crashes.
