A Socialator was a Betazoid euphemism for a prostitute.

In early 2386 Sarina Douglas used a series of encoded personal ads to arrange a meeting with her Starfleet Intelligence liason Ilirra Deel and to specify that Deel arrive disguised as an Orion female wearing a latex bodysuit with thigh high boots and a short imitation leather jacket. Upon meeting Douglas at a park in Lor'Vela, Deel remarked that her outfit made her look like a socialator. (ST - Section 31 novel: Disavowed)
