Muddy Helmet 

The term Muddy Helmet is used in reference to a film residue, coating, paste, or chunks of shit remaining on the head or just below the head of a cock after anal sex.

This phenomenon results from pounding an anus not fully cleaned of feces.

The term is often used when speaking of homosexual sex.

A muddy helmet is sometimes referred to as a "fag fuck cock collar" or a "shit kiss".

Hey. I see you are heading out with that little Brazilian faggot Andre. Don't get a muddy helmet.

Last time you pounded that faggot Andre's ass, you had to use pineapple juice to get the mud off your helmet. What does that little hissy fit queer eat anyway? Motor oil?
