A couch which was ejected from your anal cavity by way of your bowels due to an increasing amount of laughter.
Not a whole lot, that dude over there just laughed so hard he shit a couch - Ass couch
When you tired and you just chilling on the couch watching TV.
“Bernard had a long, hard day so now he’s ass couching.”
When a girl looks like she’s been sitting on the couch for to long and her ass looks bloated
That girl really has a couch ass. That thing looks bloated
A girl I used to work with at SilverCity whose ass was so big we called her couch ass, or sofa ass. Ahe had an ass you could sit on. We could never get by her at the candy bar, and always had to go all the way around the other way because her couch ass took up the entire aisle.
Couch ass was stocking the fridges with Gatorade, and I nearly sat on her, pulled her arm, and reclined on her like a La-Z-Boy.
