sofatose
When you're so high that you cannot possibly get off your sofa and do something productive. A spin off of comatose
Oh my god dude, I'm so sofatose right now. I smoked way too much.
Sofatosed
The practice of being seemingly transfixed to the sofa as a result of tiredness from overworking, overplaying or being just plain darn lazy.
Sorry I cannot possibly come to the door/answer the phone/make tea as am currently sofatosed.
