When you ejaculate in the anus and they fart a jizz bubble.

Muddy Chaplin

The sexual act of having someone take your own feces and smear it across your upper lip after violating you with rigorous anal sex, causing you to walk like Charlie Chaplin the next day. This will also result in a brown staining of the upper lip for the next 48 to 72 hours. The act is typically committed against other males while passed out drunk, and although common, not necessarily committed solely by fraternity brothers.

As Jon woke from his drunken stupor, he pulled up his boxers and waddled to the mirror, staring at his stained upper lip. He knew without doubt his roommate Greg had given him a Muddy Chaplin.

Muddy Mississippi

Where you willingly sit down and let someone shit on your head and let the shit gradually role down.

Muddy marsh

Involves a human tongue, at least two fingers, a bearded trapper and some hand goop.

I still feel squishy after that round of muddy marsh.
