Jacking it in San Diego

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."

West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.

The Poppies are at no. 17? God, a grebo band in the charts!
They're playing nu-metal now, bloody grebos!
