a magic crystal that charges up and glows when two or more bros jack off together.
Dude the other night at the lake me and my bros formed a circle around the fire and just fuckin jacked off together for like four hours. It was crazy. All of our JO crystals started glowing and the woodland creatures were howling and coming up to the fire and shit.
