Bum Catties literally translates to Attractive Females. This phrase is often used by gangsters that are trying to be fresh and original with their language selection, however the Attractive characteristic of the person that they are describing as a Bum Catty is often seriously doubtful. Bum Catties usually look like Bums (minus the catties bit, see streetbums).
