bored-beating

When you beat off out of pure boredom, a lot of times you're not even horny, you're just so bored you find yourself beating off to pass time.

(Man Thinking).... Wow I'm so bored.... What could I do?...
(Man looks down) Oh! Now I know what to do, I'll beat off and find something to do after. That's bored-beating.
