flat-backed

Describes someone so outrageously drunk they end up horizontal—usually on a couch, the floor, or wherever gravity decides they should be. Comes from the image of someone literally being on their back, flat as a pancake, because standing is no longer an option.

"Bro was so flat-backed last night, we had to roll him onto a yoga mat and hope for the best."

To smugly turn and face the opposing direction of an intended audience while having a full fledged conversation usually when it is business critical

*Three People speaking in a triangular formation; one of them is turned with their back to the other two, while the two are in avid discussion*
Lizzy- "Dick, hey I'm trying to communicate a few critical things that need to happen by the end of your shift"
Dick- "Oh, is that what you call it." Hmph (back turned to Lizzy, facing Barnaby)
Barnaby- "Did it not occur to you: You're flat-backing your boss... dick"
Lizzy- "You are a dick, Dick"
