A vulgar expression to describe the vagina. Derived from the word "vanny" (i.e. fanny + vagina = vanny), with the added expression "cunty" for that extra touch of vulgar. Rolls of the tounge quite well.
Warning: Use with caution. Not advised during sexual intercourse unless your partner is a dirty / kinky bitch. Also beware of using this term in public. People will think you're a nut case.
Hey Bro, I'm feeling horny, let's get drunk, go to town, and spit roast a vanny cunty!
