A girl in a lesbianrelationship who is usually a bottom. She likes to recieve rather than give and she is also most likely to stop texting when she sees you're also typing.
This usually has a negative connotation. In some situations it is an act of laziness but in others it is a girl who lays back and is willing take whatever her partner wants to give her. In this case it is a submissive partner that is willing to give all the control to her dominant partner. Normally this type of relationship is a mutual agreement so that both are getting what they want.
(1) A girl (of any sexuality) who likes to receive sexual pleasure, but does not often return the favor herself.
(2) A (usually humorous, often self-deprecating) term to refer to a gay man who almost always prefers to be the bottom, and often is fairly lazy/self-serving about it.
Both definitions stem from the idea that they just want to lay back on the pillow and be treated like a princess.
(1) She's such a pillow princess, she never wants to put any work in for the other person.
(2) Yeah, he's kind of a pillow princess, total DIVA in bed.
