1 definition by Mr. Hill

After vigorous anal sex, when there is a thin layer of doo-doo butter still present on the penis, the act of sprinkling powdered sugar on said butt-butter and assertively ramming it down the woman's throat.
Inspired by the Chex snack, Muddy Buddies.
Last night I gave Kari the Muddy Buddy until her face turned Blue.
