Buttonhook 

during sex, doggiestyle of course, slipping two (or three) fingers in her butt, and picking her up off the ground and/or bed whilest screaming "BUTTONHOOK!!!" or "ZOINKS!"

I couldn't hear Jen cry when I gave her the hucklebuck, because I was of course shouting, "BUTTONHOOK!"

buttonhole 

To accost or detain a person in order to force them to engage you in conversation.

Man, I dropped by this party last night to say hey to a friend, and my ex was there, and before I could get out she totally buttonholed me in the foyer and starting crying about how we should get back together. It was messy.

Buttonhole circumcision 

A slit in the dorsal surface of the foreskin that the head of the penis is pushed through. Technically it is a piercing and not circumcision because the cut is not all the way around, and no tissue is removed. Healing is faster than after regular circumcision because if an erection occurs it helps keep the wound closed, rather than splitting stitches. No sensitive nerve rich tissue is lost, and the head does not dry and loose sensitivity due to a process called keratinisation because it can still be covered by the foreskin after healing is complete. Foreplay and masturbation are greatly enhanced and the foreskin ads extra stimulation for the woman during intercourse, kind of like a ribbed and textured sex toy.

This guy had the weirdest cock I ever seen, looked like it was cut, but there was this flap hanging down under the head. He said it was called a buttonhole circumcision.

Marvin asked me if I changed my number, because I haven't been answering his texts when he asks for food. He's such a butthooker! He needs to butthook a job.

Buttoncock

Having a cock so small and retracted that it is not even worthy of being referred to as a cock. Rather, it appears to be a one-holed button against the pubic region, with a very slightly pronounced rim that is the skin around the shaft. The actual bulb of the penis is sunken below this rim and appears to be no more than a fleshy button like that found on a sweater or shirt.

My friend SamERazar is such an unfortunate soul. The poor bastard can not get laid for being laughed at. Apparently his cock is so small that it hardly protrudes from his fat body. Sam therefore will be referred to from now on as Buttoncock.
