Buttmurder

The act of having your anal cavity completely destroyed possibly resulting in death.

I was so mad at my ho that I buttmurdered her with a kfc spork.

Or

Scott: Awe man I feel like I got buttmurdered last night.

buttmugger

Thievery of the anus.

Stay away from him he is a buttmugger. If you deal with him you will no longer be an ass virgin and chances are you won't even know it. He is that slick!

buttsurfer

A member of a clueless freshwater species known as the river kayaker who ventures out of his element and into the lineup thinking he or she can actually surf, with no concern for the hazard posed to real surfers by a huge uncontrollable boat and paddle. Obviously afraid of salt water, as indicated by presence of nose plug, helmet, and life vest.

"Hey, bra, what's up with that buttsurfer crowdin' the lineup? If he likes sitting on his ass so much, shouldn't he stay in his cubicle?"
"Dude, I know, he totally ran me over when he got caught inside on that big set!"
