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."

Flat Earthing

When an incoherent person who believes the earth is flat and everything is a lie rambles on about their whole belief on how it is "so obvious" that some big company would pay billions of dollars to lie to every civilian on the globe.

Flat Earther: "If the earth is round, then how come we have not been tossed into the ocean yet?"
Intellectual: "Please, stop flat earthing."
