Helmet hair

Messy hair. The flat, lifeless appearance of hair, or wild, 'uncontrollable' appearance of hair when a motorcycle helmet is removed. Most affected are women and it's a common problem for those with a coiffure.

When she took off her helmet, everyone could see she had 'helmet hair'.

Her 'helmet hair' took a lot of brushing-out before her hair looked nice again.

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."
