Urban Pi 

Irreverent or politically incorrect math definitions on and about the number π, most of which stand zero chance of ever being published in a school textbook, because they are deemed inappropriate or unsuitable to the immature or puritan mind, or to those with a poor sense of humor.

How could pi enthusiasts be deprived of a lexicon of urban pi terms or phrases just because some of them are allegedly blasphemous or irreligious or preposterous?

Newark has sweet urban piste. It rarely snows but that hasn't stopped me from grinding every handrail from City Hall to the Iron Bound.

urban pimp 

The new type of pimp. Urban pimps are whiter than G's. Dark skins are usually considered to be gangstas if they know how to be chingy while the urban pimp is chingy and knows how to hustle. Urban pimps do not dress like the old genration of pimps. They wear brand new clothing lines like PW, have loose clothes, have bling and the biggest change, have more respect for their woman. Urban pimps can be doing the same activity as G's but have the brains to know how to create buisness and have a real rep for themselves while not falling in a less-than-hip class. The new style emurging on the streets.

"yo did ya see dat white chingy gangsta on da street?"

"Ya dawg but dat ain't no gangsta, dat's an urban pimp"

urban pirate 

A person that lives in the city, whether it be big or small, or elsewhere that is not on the open sea, that partakes in the ritual of stealing anything he can get his hands on.

In the plural sense, a band of urban pirates may go and steal things because they are bored, not just because it makes them feel good.

John: I'm bored.
Kyle: Me too.
Sarah: Me too.
John: Let's go steal something!
All: Okay! *Urban pirates get up and leave their dwelling to plunder a street sign, rum, or whatever else may look appealing to them at the time*

Urban Picnic

As one is sitting in traffic with nothing else to do, sandwhiches and beverages are to be provided just as a picnic might occur in a grassy park.

Brad and Lauren were stuck in traffic, so they decided to have an urban picnic. It was romantic.
