To "gangsta" it up, you may also say "jinglin'" as opposed to "jingling." The "jingling/jinglin'" is done to one's penis/testicles as they are beat with the force of a hand and "the change" is the semen that is being prepared for launch.
Logic: If a warehouse of semen can be called a sperm bank, then shouldn't the semen technically be called money/"change"? And if one jingles bells, which sounds like "balls," why not say that one can "jingle" balls, "jingle" balls, jingle them "all the way"?
Man: Dude, why are your hands bouncing around in your pockets?
Dude: Man, I'm just jingling the change!
Man: Niiiiice!
Man: Dude, Jessica Alba makes me jingle my change all night long.
Dude: Man, Tila Tequila jingles my change IN PERSON!
Man: No way, Dude!
Dude: Yes way, Man!
Mainly a tradition of the D-Club, "jingledinking" is the act of tying holiday bells to your semi-chubbed shaft and dancing (similar to the Ribbon Dance, but without the ribbons) around a holiday object (e.g., Christmas Tree, Menorah) in a completely heterosexual way.
"Hey, guys. I know we're all straight, but since it's the holidays, we need to celebrate. Whip out your dink and let's jingle. It's the season for jingledink."
