Dunch

{dA rather extreme form of Ass Spelunking occurring after lunch but before dinner. The extremeness being that it often involves shit covered orifices and brown mouth hugs. This can occur between two men/two women/man & woman. If more than two parties are involved it becomes a Group Dunching.

I dunched the shit outta that sorority chick last night!

Peter got all mad after we decided to dunch and I accidentally got some poo into his eye which gave him pink eye.
