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.
You are a cuntsmack. You're fucking dumber than a cuntsmack.

Get the cuntsmack mug.
Originated by the Lahs, a cliquey couple of fine ladies, "cunt smacking", is to smack ones vagina.
