noun, circa 1900, USA ... in use from the turn of the century to the beginning of Prohibition; a lower class Bowery urban type saloon-dance hall-tavern catering to gamblers, con-artists, pick pockets, prostitutes, women of easy virture, homosexual pansies and the like. A place one would go slumming for a good time. An urbanized version of the Wild West Saloon, but seedier, a dive or joint. Fun, like a ride down a slide in a children's playground.
We always pinned our money to the inside of our knickers; that slide was full of classy dips and burglers.
