Mud Helmet
The after effects of inserting the penis into the dirty ass of another. When the penis is pulled out the tip of the cock is lightly covered with poo thus giving it the look of having a mud on the helmet.
Man I was hittin her in the ass and when I pulled out I had a mud helmet.
mud on the helmet
A homosexual term for when one guy butt fucks another guy. The "mud" is a crude term for shit in the bottom's anus. The "helmet" is to describe the shape of the head of the penis. When the top (helmet) rams his dick into the anus of the bottom, he gets shit (mud) on it. Thus, "mud on the helmet".
"I fucked my boyfriend so deep I got mud on the helmet."
