The Yeti 

The act of ejaculating in your partners chest, then ripping off her pubic hairs and placing them where the baby yoghurt was splattered on, then make your partner scream and run around in circles shrieking like a Yeti.

''Man, i gave that prostitute the Yeti last night!''

The Yeti Yank 

While engaging in anal sex with a hairy fellow, one would grab his back hair and yank until the fellow makes a peircing cry of that of a yeti.

While Ben was engaging in anal sex with Wade, he proceeded to yank his glistening back hair until Wade screamed like a yeti. Thus, the Yeti Yank.

Betty the Yeti

A term given to a woman with very hairy forearms, sideburns and a 5 O'Clock shadow on the upper lip. God only knows what lies underneath the clothing.

I saw a woman with a full on goatee. Betty the Yeti must have the day off from the Circus Freakshow.

shreddi the yeti 

Large, friendly, furry animal known to giggle incessantly. Became extinct because it had no known skills. The final known Yeti died of peanut allergies after being shot by a security guard with a paintball gun.

Wow, man, you are as worthless as Shreddi the Yeti
