A bottom girl, a bottom woman or bottom bitch, sits atop the hierarchy of prostitutes working for a particular pimp. A bottom girl is usually the prostitute who has been with the pimp the longest and consistently makes the most money. Being the bottom girl gives the prostitute status and power over the other women working for her pimp. However, the bottom girl also bears many responsibilities. In U.S. v. Pipkins, the Eleventh Circuit described the bottom girl’s duties as "working the track in her pimp’s stead, running interference for and collecting money from the pimp's other prostitutes, and looking after the pimp's affairs if the pimp was out of town, incarcerated, or otherwise unavailable". Similarly, the PIP Training Manual explains the bottom girl’s obligations may include handling finances and training and recruiting other prostitutes. Bottom girls may also instruct and advise new pimps on the ways of the prostitution business. The Pimp Game, a published instructional guide for pimps, compares the bottom girl to a coach in the NBA, i.e. a former player who "knows the ins and outs of the game", and explains that, like the NBA coach, she is "the least paid on the team, but the one who works the hardest". She also has the most interaction with her pimp's prostitutes, giving them "pep talks" and keeping them in the game.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.

The most experienced hoe in a pimp's stable.

The one girl the pimp reserves for himself, or the player's favourite girl.

BottomBitch means the best. A bottom bitch is usually the baddest bitch who has been fuck’n shit up in a good way and consistently throws down. The bottom bitch doesn’t want, but is constrained with status and power over other bitches. However, the bottom bitch walks a lonely gangsta road, just her and her bitches & bros. The bottom bitch makes the tough decisions; takes responsibility for themselves; and shows what’s she knows to her bitches & bros.

A pimp's main woman. The one he settles down with when they decide to get out the game. A lioness who he loves and trusts. A real down ass ride or die type bitch.

A bottom bitch is a down ass chick who is down for her man.
