Buttjerk 

While getting fucked in the butt, missionary, the current buttfuker grabs the penis hard with two hands and continues to buttfuck harder while jerking at the same time.

I was buttjerking so hard with my bud yesterday, we cam at the same time!

butterkeks

A result of using too much lubrication, and the uncomfortable feeling in your trousers afterwards, often used in homosexual circles.

Tarquin: 'Quentin is walking a little strange, do you think he's hurt himself?'
Kanye: 'No, he's got butterkeks, he used an incredible amount of lube taking that enormous sausage up his ring piece this morning, and didn't have time to douche'.

the rogo butterknife

When you are pounding a chick at an intensity of like, 7 out of 10, and she tells you to go harder -- and you're like, "what? I'm already 7 out of 10ing you" but she insists. So you amp it up to 10 out of 10 and then your penis slips out of her vagina and stabs her in the butt hole creating a big bloody mess, causing you to stop having sex with her before you throw up.

Last night I brought this chick home and i totally gave her the rogo butterknife and now I have to wash my sheets.

butterknife emo 

A person who pretends to be emo only to get attention and people feeling sorry for them. The term comes from the idea of someone trying to cut his/her wrist with a butterknife.

I don't want to hear your whining. Your just being a butterknife emo again.
