A cute way of explaining masturbation or" jacking off" to children during that the talk that every parent dreads, the talk about sex and junk.
Alan's Dad: Alan, when a man lacks a sexual partner the man will do something called "jackie offy" to relieve himself of thinking about sex all day.

Alan: Dad! I know what Jacking off is, I'M 27 years old jeez. I do it all the time. And the scientific term is "self induced ejaculation".
