Slang term for masturbating with another man, not for sexual gratification, but towards the end-goal of charging mysterious power crystals that the maturbatateurs wear. It said the crystals glow white "while jerking it with a bud" and that they give the wearer confidence at work, home, in social situations, etc.
"Hey bro did you bring your crystal? Then let's charge up and JO!"
