A dental crown that has been dislodged, swallowed, retrieved from fecal matter, sterilized & re-cemented in order to avoid costly replacement. While indistinguishable from others, you willalways know where that tooth has been.
"Damn! I just swallowed my crown! I better get a new one."
"You do realize a new one is like $900..."
"Damn! Now I'm gonna have a poo tooth! Where are the baggies?"
Guy 1: You poo knuckler
Guy 2: Do you even know what that means?
Guy 1: no, what?
Guy 2: a poo knuckler is when someone shoves a fist up your butt!
Guy 1: No way, you just pulled that definition out of your ass Guy 2: Literly!
