Whore
Someone who will sleep with anyone.
This term has a long history of being used pejoratively to describe sex work so the role sometimes suggests a more transactional style of dynamic.
The word 'whore' is considered a slur. Some people have chosen to embrace this role as a way of reclaiming the word for themselves in the same way that terms like slut have been reclaimed.
