Dirty Chowder

The act of sticking your own finger up your own ass and then wiping said finger across your upper lip.

Scott: I don't remember Derek ever having a moustache? When did he grow that?
Kelly: He doesn't. I heard he sticks his finger up his ass then wipes it under his nose. It's called the Dirty Chowder.
Scott: That is one sick fuck!!!
