The act of publicly masturbating while on a street corner in San
Diego, usually after having led a social justice campaign, and gone nuts from the pressure. The term was coined by South Park which satirized the founder of Invisible Children, Jason
Russell, for engaging in the aforementioned act, which pretty much destroyed any momentum his movment, Kony
2012, had left.
Kyle: "Well when you're naked and jacking it in San
Diego, don't say I didn't warn you."
Stan: "What?!"...
Barber shop trio: "Jackin' it, jackin' it, jack-ity jack, spankin' it, slappin' it, spank-ity
slap!"...
Mayor: "...why not try jacking it on one of our city streets? San Diego,
cum, take a load off."
