Originally the act of smacking the cunt, but more oftenly used as an insult. Comparable to other insults like dumbfuck or dumbshit. Can also be used as a noun.
My lady friend took an inordinate amount of cock shots and uploaded them to my work computer. At the next business meeting, I hooked up the projector, which let my subordinates view my unkempt cock. Since the cockshow, my career has been in drastic decline and led to severe cuntpression.
