An ancient Chinese kung fu move which involves a male or a female (hopefully not) whipping out their dick and using it to block a karate chop, hence the name Cock Block. It has the potential to hurt the owner of the dick, but usually ends the fight with the owner of the cock being victorious. This is due to the fact that the other fighter is afraid (usually) of touching the dick, because they don't want to become gay by doing so. If you're fighting a girl.... um i guess you're screwed

An application that chat roulette needs to add that literally blocks cocks from the screen. This would entail a cock-identifying application that would need to work better than facebook's face recognition feature. It would also cut down on 90% of chat roulette users.
He was going to flash people on chat roulette, but the new application cock blocked him. He's gone back to flashing girls at parties.
