It happens usually when there's nobody around and you're in a dark room. Most likely, soon after you sit on the couch you will ask "Helloooo?" to make sure truly nobody is in the room. On occasion, someone will crack up laughing at your stupidity and give away their hiding place.
Example 1:
Person 1: "I'm just going to sit on this couch now.....helloooo?"
Person 2: "......HAHAHAHAHAHAAAHAH"
Example 2:
Person 1(on the phone): Yo man, I'm sitting on a couch right now. ... wait up,...hello???
Person 2: (on the other line): "ok then.."
Person 3(hiding): "AHAHAHHAHA YOU'RE SUCH AN IDIOT"
Person 1: "I'm just going to sit on this couch now.....helloooo?"

Person who spends too much time licking a female's private parts that he/she gets no work done and is consequently failing at work/school. The person doing this would have their chin on the couch.
"That guy is always failing his courses because he spends all of his time licking box. He's a couch chin."

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.

Noun: A place of safety or refuge from social outcast, embarrassment, and ridicule constructed via cushion, fabric, and puffs; an inlet of refuge from post-intoxication induced stupidity and promiscuity; the vessel in which one watches horror films, psychological thrillers, or consumes the Domino's pizza (occasionally by the grace of sirmarmasir, all 3 at a time).
"Yo gypsy, you think you're in couch safety right now? You're not - get back to the frialator and don't be stealing no McNuggets!"
"Judy enveloped herself in the swaft of couch safety and began her on-demand rental of 'The Ruins'...'Ah' she thought to herself, 'what a perfect Sunday afternoon'."

It’s when you & your BFF kneel on any given couch, buck nekkit, facing aft towards the same direction; with each participant having their head laying down & rear up, while having a third miscellaneous person tongue each bung, taking turns in between sets.
“Let me get this straight! A polish couch is when you & your buddy are face down- ass up, but you only get one dedicated tongue?” - Dale M. Pace
