1) Something 11-17 year old guys do because they don't have anyone to have sex with.

2) Something you watch your sister do after she showers

3) A way to get the erection you get every mourning to go away

4) For men, using your hand to cause an orgasm

5) The only sleep over game for boys other than hand jobs.

6) The favorite activity of my both me and my six year old brother.
Jack sat in his room his room, practicing his favorite sport, masturbation, rubbing his hand up and down his cock until his sister walked in and gave him a new means of pleasure.

The act of touching oneself to produce a favorable feeling in the groin area. Usually accompanied by some sort of mental, visual, or audio stimulation to assist in reaching climax.

jerking off; spit-shining the old water pump; waxing the brass candlestick; beating off; playing cards with only one hand on the table; riding the quarter-horse; joining the mile-high club, solo-aviator division; giving in to the hand police; self-actualization; fully realizing your potential
No honey, I don't want to tonight, I'm tired from watching Oprah. Why don't you just go masturbate?

That dumb broad got me all worked up and left me; so I had to spit-shine the old water pump manually if ya know what I mean.

Sometimes, when I wake up, I have an erection, so I have to beat off until it goes away. Sometimes, it comes back so I beat off again until it goes away. Once, it kept coming back so I just chopped it off. It hurt bad.
