Knuckle Cock

Finger fucking a guy's girl under the table at a bar while he is at the table, then punching him in the face afterwards, karate style, with two fingers, like Chuck Norris?

I knuckle cocked that douchebag and took a shot of Jack to top off the night.

Knuckle Butler 

As heard on the podcast All Fantasy Everything. A Knuckle Butler is a mutual agreed upon hand job with no expectations of receiving more.

Jimmy expected to get a French Blowjob from Sally at the end of their date. But by the end of the date they agreed on a knuckle butler because they were exhausted

Knuckle Neckin’

When you have a stoma and that is plugged up and needs someone to shove a finger down knuckle deep to clear it out so they can breath.

Debbie, “Stan you ok?!”
Stan, “ndbbsxibdei” (mumbled but quiet)
Debbie, “He can’t breath!”
Paramedic, “move aside ma’am his stoma is plugged up, he just needs a little knuckle neckin’ “
-Knuckle Necks-
Stan, “I can breath!!”
Paramedic, “Yeah I got in there deep. Your welcome” -walks off with a boner

Knuckle Cherry

A term used amongst lower socio-economic class people to denote the breakage and fracture of knuckles to the point of deadening the nerves in the area, permitting one to punch hard objects with minimal injury due to Wolff's Law. The only recorded usage is in the homeless regions of central Ohioans, but usage probably extends further.

"You haven't popped your Knuckle Cherry yet? That's your problem. Ya gotta pop ot and it hurts for days then ya can hit harder and can't feel it, Joe."
-Big Mike
"Oh. Sounds painful. I'll pass."
-Joe
"Well, ya got to. I don't want you fightin' no more but ya gotta be ready. You're a brother."
-Big Mike
