VERB:
To listen to one's stereo while simultaneously lying
on the couch watching television with the sound turned down.
This is based on the fact that those who simply lie
on the couch watching TV are couch potatoes, therefore they must be "baking." It's even worse if they're doing two worthless things simultaneously: hence, they are "double baking."
It follows that they would be double baked couch potatoes for those who care.
"I was so bored that I got
on the couch and spent the
evening double baking with 'Seinfeld' and 'Exile on
Main Street.'"
"Are you just gonna lie there double baking, or are you goin' with me to Joey's?"
