Flat-screen T.V

What's left after someone opens a Carbonated-screen T.V and then just let's it sit there for a really long time without using it.

Flat Earther

A reminder that as much of a failure that you are, there is always someone more disappointing than you.
(although you are currently on Urban Dictionary, so maybe not so much).
