donkey conch 

A huge vacuous vagina, the inverse of a inverse of a donkey dick.

Dude, that chick is such a slut. I'm sure she has a donkey conch... Go for it if you want to play some donkey conch. I bet you could throw a barrel up that thing.

donkey conch 

while similar to a 'donkey konk' or 'donkey punch', there is a slight difference at the end. Instead of punching one's partner in the back of the head, one finds a conch shell and wacks it over one's partner's head a la lord of the flies.
