Muddy Mandel

The act of cunnilingus while the receiver defecates on the toilet, thus leaving a streak of feces between the chin and lip of the performer, which resembles Howie Mandel's soul patch from the mid-00's. Analogous to the blumpkin.

Emily: I heard Brian gave Tiffany a mean muddy Mandel for their one year anniversary!

Stephanie: Tiffany's so lucky - she found a keeper for sure.
