When someone takes amphetamines and makes the mistake of sitting down for too long. They have now become one of the couch and there usually is no return.
The feeling is usually rather bliss but also very annoying to the people they were with who did not get stuck and just wanna get down and boogie
Person 1: Oi lets go dance
Couch cooker: Nah man, just another ciggie plus this couch feels good.
Person 1: Bro, get up or you're going to get couch cooked.
