The BETTER name for all Blockbuster stores.
Cockbuster tried to scam me into paying $30 dollars for a video I returned and they didn't scan in.

This is when a man cums so hard having a wank that the sperm comes out so hard, the the bellend pops off the scrotal zone.
My girlfriend tossed me off and I got so exited, I ended up having a Cock Buster. My girlfriend wansnt very pleased with my bellend popping into her nostril.
