A Desk Flip Rage Guy meme.
Desk Flip Rage Guy is a rage comic character flipping a desk over in pure fury, papers flying. Captions describe the exact moment patience runs out - a game crashing just before you saved, a website asking you to log in again, the printer jamming on the last page. It's the drawn cousin of the ASCII table flip (╯°□°)╯︵ ┻━┻, and the meme for losing your temper at small, maddening things.
