Hobby prostitute
The colloquial and often derogatory term “hobby prostitute” usually refers to a person who offers sexual services privately or alongside another occupation, rather than as a full-time profession. The abbreviation “HH” is sometimes used in this context in personal ads or on erotic platforms.
The term is strongly judgmental and can sound dehumanizing. In factual or respectful contexts, more neutral wording is preferable. In any sexual-services context, legal requirements, consent, and clear safety agreements should always be observed.
