Adjective describing someone who is in a very lazy mood. Does not want to get up from the couch, or does not want to disturb what they are doing.
Also, lack of excitement which can lead to a buddahlike state of bliss.
1) Yeah, so the Steelers are on tv and my dad's all fat on the couch... so I dont think I can get a ride out with you.
2) My dog is bein' fat on the couch right now, and if you came over I think he'd be pretty happy.
