What is the term used for a person who makes prostitution their living?

The term for a person who makes prostitution their living is "pimping." This refers to an individual who manages or profits from the sexual services provided by another person, often establishing a relationship that involves control or exploitation. A person engaged in pimping typically may provide protection or other support to those working under them but ultimately benefits financially from their involvement in prostitution.

Pandering is the act of persuading or enticing someone to engage in prostitution, while solicitation refers to the act of asking or trying to engage someone in prostitution. Loitering, on the other hand, involves lingering in a public space with no apparent purpose and is not specifically related to the act of making prostitution a profession. Thus, the correct choice centers on the business aspect of managing or profiting from prostitution, which is encapsulated by the term "pimping."
