If it existed, it some would say it to be the exact opposite of Urban Dictionary. In reality, Urban Dictionary is just a subset of a truly Urbane Dictionary, ideally conceived.
One would perhaps not expect to find offensive slang, misspellings or incorrect grammar in the Urbane Dictionary. Urban Dictionary however? Par for the course, old boy. The Oxford English Dictionary (OED) is quite urbane, though congnizant of urban slang. A good, truly urbane dictionary, however, would not seek to be prescriptive, it would faithfully report usage, both vulgar and sublime, without overt judgement or censorship. Thus, the OED and Urban Dictionary truly need each other, in the grand scheme of things.
Playing in the outdoors in an urban setting - parks, open space, trails, walking between art galleries, museums, and shops; dining al fresco - anything without a ceiling. Just because you live in the city doesn't mean you have to be a couch potato!
