Mississippi Mud Muffin

A possible delicacy during anal sex. A Mississippi Mud Muffin or MMM is the excreted nickle-sized (or larger) poo that may be produced after quickly pulling out during anal sex that is then orally consumed by the penetrated partner. The consumer must say “Mmm!” after consumption for it to be a true Mississippi Mud Muffin.

The chick from accounting totally had a Mississippi Mud Muffin last night! I knew she was a freak!
