Bottom or Bottom is a slang term of the GalDrift Community that found its way into the language use of law enforcement agencies and Social Service providers.
It describes a person or individual at the lowest end of the social structure. A Bottom is almost always a Non Citizen and more often than not, a minor runaway that is not a Citizen and has a criminal record. Bottoms can be found at large space ports and in large Multi culture Metro environments such as Pluribus , Midway , Blue Moon , Ross etc.
Since they do not officially exist, they are sometimes subject to the cruelest fates. Such as slavery, sexual exploitation and cani-trade.
The Black Leather and Gum Society uses the same term to describe voluntary slaves and submissive partners.
