Helmeting

Like the similar definition on this page, the act involves inserting one's head into the particular orifice. The original example that I've seen, and most others have also seen, is a video of a bald man putting his head (up to his ears) into a woman's vagina.

Did you see that video where that guy put his head in that chick's pussy? That's gotta be one seriously loose hole for helmeting.

Compression helmet

Usually used in sentence sarcastically, a Compression helmet counteracts and protects against the effects caused by the "fun theory". The "fun theory" states that if an individual has too much fun within a short amount of time, consequently, said individuals head will blow up.

Jon: So, what are doing on this fine Friday night?

Fraser: I have to go to bingo with my 94 year old
grandmother.

Jon: Better bring your Compression helmet!

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."
