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.

jump off

Someone that you FUCK on occasion that you have no ties to. (Usually, one or both involved are married). Don't put any feelings into a jump off because you walk into it knowing that you can't get anything from it but a good FUCK! If you catch feelings, you will get hurt!!

one-off

A person you only plan to have sex with once. A one-night stand.
He's just a friend but he's cute enough that I would consider a one-off.

Wanking off

1) masturbating
2) Being lazy.
1) Mom was horrified when she caught Jimmy wanking off to internet porn.
2) Would you quit wanking off and get back to work already?
