plunger

when a man takes a small shit in the mouth of his partner and then procedes to mouthfuck her (/him?), in a motion that could be interpreted as the male trying to force the shit down his partner's throat with his dick, as one would use a plunger on a toilet.

i did a plunger on that fat bitch and she almost died.
