Pay Baby
A female, male, or "other," who, (unlike a Sugar Baby, who may provide companionship and other, "non-sexual" services;) provides sexual services for financial gain. They charge according to time spent on services. Usually charge in 15 minute increments, hourly, three (3) hr periods, or the entire night, (which could be anywhere from eight (8) to twelve (12) hr's. They often will advertise on social media sights and often work with a partner. When one partner engages in an actual relationship with someone, the other partner would then book their appointments, (scheduling around the person they are dating,) who usually has no clue who they're really dating; and verbally communicates their partner's appointments to them so there will be no proof; encase the person they are dating was to catch on.
