Fridge Headbutter 

A person who is so unfortunately ugly; they appear to have spent a whole week, none stop, smashing their face against a fridge to create the full mangled look. For an added feature, the same monster can sometimes complete their metamorphasis by kissing a hot iron.

Tony: Hey Tez, i think we should get the fuck out of here, theres a right beast approaching!

Tez: Don't worry Tony, it's just Vanessa, She's a fridge headbutter!

Tony: All the same mate - I'd rather leave before this ugly bitch takes us hostage.

This is when two circumcised dudes mash their pecker tips into each other. This is usually an aggressive (not gay) cockfight for dominance.

The party was going swimmingly until a couple dudes started German Headbutting each other!

headbutt the buffalo 

An euphemism for cunnilingus, oral sex, an act performed by a person on the vulva and/or vagina of a female, the opposite of fellatio. The term was created by “The Man” and has become popular due to its frequent use on the legendary podcast Slacker and The Man. It is important to this podcast not to offend their sensitive listeners, many being doctors and lawyers.

Terminology: A headbutt is a strike with the head, typically striking a sensitive area of an opponent. A buffalo is an animal that is the size of a very large cow, with shaggy, long, black/brown fur. If you haven’t figured it out yet, buffalo is another euphemism for that treasured part of the female anatomy, the vagina. Put the two together and it is easy to create an image in the mind of a man charging with his face first into a lady’s lap - the beginning of oral sex on a woman.

Mashers: "I have a 30 minute minimum when it comes to sex."
The Man: "Does that include headbutting the buffalo?"

The Man: "Ever headbutt the buffalo?"
