butterknifer 

taking a shit so long that one is unable to flush it down the toilet, thus requiring a butter-knife to cut it into smaller pieces in order to flush properly.

Dude, I've been holding it in all day and just dropped one hell of a butterknifer.

Gary, you really shouldn't be eating a box of granola bars a day, you might clog your toilet with all the butterknifers you probably take.

That butterknifer is over 14 inches long! Damn!

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.

Cinncinnati Butterknife 

The act of pooping in a condom and then using that condom to have sex with a girl.

"Yeah man I did"

"You sick bastard"

amish butterknife 

The ultimate in Shadery and Nyaaaaaaaaadom.

Pertains to multiple men ejaculating into a five-gallon bucket. The bucket is them passed to an Amish person to be churned into butter in a butter churner. The resulting colloid is then applied to a butterknife, and then swiped across the face of the victim.

When Eskimo passed out last night, we called up John Yoder, scored some "Amish butter," and gave Eskimo the ole "Amish Butterknife"
