Jack Off
To play with your dick until you cum.

Jack Off
Male masturbation; a man rapidly and repeatedly rubs his hand up and down his dick until he hits orgasm.

Done when horny, when porn is plentiful, or to get rid of a boner in class.

Jason had a huge boner in science class, so he ran to the bathroom. But there were a whole bunch of other kids with their pants and boxers around their ankles and their dicks in their hands, masturbating furiously.

There were three guys at each of the urinals, one on each toilet and two more standing in front of each. There was another pair at each of the two sinks, and at least fifteen spread out across the floor. They all groaned as they shot their loads across the room.

"It's a jack off epidemic!" Jason stood wide-eyed as his dick stretched hard against the fabric. He quickly dropped his jeans and plaid boxers and began to jack himself off in the doorway.

More guys pushed against him, trying to get some privacy to jack off in. He felt three dicks strain against his back.

He felt his dick grow larger and larger as more guys pressed against his ass.

Then he woke up. He looked down at the puddle of sperm in his hand, then quickly pulled his boxers back up and laid down to sleep.

Jack Off
if you're under 13: you're not cool enough to know what it means. come back when you wake up and its sticky in your danger zone.

if you're over 13: why the FUCK would you need to look up the definition of "jack off?" did your balls not drop yet?

why the hell would any guy who's hit puberty need to look up what "jack off" means?

Jack Off
Can be used as a noun to refer to a guy who wastes time, is a complete loser, and cannot get anything done. This guy may well be popular with friends, the ladies, and whomever he meets, but has never accomplished anything and never will. Anything he has tried to achieve has ended up in disaster.

That Kramer on Seinfeld sure is funny even if he is a complete jack off.

Steve, did you complete the final report so you can graduate from high school next week?

No. I'm such a complete jack off that I never get anything done.

Smoking pot will really just turn you into a lazy jack off.
