Daffin
Daffin is when your butt is so full of sh*t you're leaking out of both ends and your penis is doing the conga.
My friend Daffin'd so hard he started singing show tunes in the shower.
I Daffin'd at the party and tried to eat a whole pizza by myself.
My dog Daffin'd on the couch and now it smells like a sewer.
