jerk-off

A contest in which two men must stare at each other while fapping. The first man to look away or cum loses. Blinking is safe.

“John, I challenge you to a jerk-off.”
“Alright, Jack. Where? When?”
“6:00a.m. this Saturday. The lot back behind the Giant.”

Sketch off

To be present in a group of friends or acquaintances, and suddenly disappear from said group, never to be seen again that night.

"Dude, I was talking to you last night, and then you completely disappeared."

"Ah, sorry man, I sketch off at the worst times. I'm going to the doctor next week to see if I have sketcholepsy"

dust off

Dust Off or Canned Air is sold in office supply stores. Its intended use is to clean dust out of keyboards. But it does a much better job of clearing out your mind if you place the nozzle in your mouth and inhale the toxic air. Hold the fumes in and exhale as the world starts to go Wah Wah Wah. Make sure to hold the can right side up so you don't freeze your tongue off. This is the devil's drug never do it. It is highly addictive and highly brain damaging.

My friend was doing dust off in his kitchen when he passed out, fell onto his dishwasher and broke it.

punch off

Punching off is the act of gripping one's penis between the middle and ring finger. After getting a good grip, you then punch the balls and scrotum as hard and fast as possible until ejaculation is reached. It is a new form of masturbation, which has only recently been started being practiced, originating in a seedy Jamaican village.

My penis felt extremely good after punching off, however I now have an empty scrotum.

I was having feelings of extreme pleasure and pain after I had a punch off.

off by one

Off by one or OBO is a common error in computer program whereby a loop executes one time too few or too many. It occurs most commonly with complex vector or matrix scans.

Programmer 1: This program doesn't work. Take a look and see if there's anything wrong.
Programmer 2: Oh, this for loop is OBO. You aren't scanning the whole array.
