A couch queen is a person who typically lays rather motionless during sex. See also Starfish. It normally makes for a rather underwhelming sexual experience. But it can be very arousing and stimulating if someone has a particular fetish for this, or for example if they are dominating.
I really was looking forward to having a good time with this person, but they turned out to be such a disappointment, they were a couch queen.
A voluntarily kept woman who has no shame in not contributing anything to a relationship outside of the bedroom. Unwilling to go as far as to maintain the home or cook while her husband makes all the money. Assumes the role of resident couch potato and entitled brat.
"My wife is a couch queen. She's convinced her performance between the sheets is enough to earn her a free pass on contributing anything further to our relationship. She's reduced her days to sipping White Claws while watching F-boy Island while I'm slaving away at work 11 hours a day."
