urban chestnut
An Urban Chestnut is what you leave on a hookers blouse (or any city dweller) when she blows you off in a St. Louis alley. Also, a St. Louis craft brewery which you may have visited before buying the BJ and depositing the Urban Chestnut.
Man, I had a couple of beers last night and totally gave my girlfriend and Urban Chestnut behind the Pita Pit.
