1. To wank in a public place, with or without others knowledge. The true master of the urban wank can do it in a place so obvious that no one takes any notice.

2. Much like public sex. But without the partner.
"Oh my God, is he doing what i think he is!"

"Urban Wanking? No surely not in such in obvious place" *Glass elevator*
