A sexual fetish or sexual move where after pooping, one does not wipe well enough and leaves poop on the butthole then gets their ass eaten
My buddy is a little weird, he asks girls to not wipe so he can get a rusty drain.

The act of urinating inside his/her anus and they stand up and let it drain on you.
