A type of Brothel worked by only the oldest, ugliest and most disease-riddled prostitutes. These women can't do business with regular clients as they are so repulsive no one would pay for them. Instead they are condemned to a Briggsy Brothel where only the oldest, ugliest and most disease-riddled clients go. Regular prostitutes won't do business with these clients as they are so repellant. Thus the Briggsy Brothel matches up hideous hookers with repulsive johns. The BB is such a niche profession that the hookers are frequently idle. These disused prostitutional wastes pass the time by exchanging treasured possessions such as genital warts and fanny slugs.
What's that building the Dwarf's entering?
Aah that'll be a Briggsy Brothel.
