A girl in a lesbian relationship who likes the receiving but doesn't like to do the giving. This is the same as a pillow queen aka the bottom in the relationship.

(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.

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.
