From Japanese doya-gao (ドヤ顔, どやがお). A smug face made after a win or something epic (or not). Doya-gao, because of this nature, tend to be irritating.

This word started in Kansai stand-up comedians, and became popular in the M-1 Grand Prix 2006, a manzai tournament. It was adopted quickly on the Internet, to the point where they had a whole TV program named with the word.

The Germans have a distinct word for it. It is "Backpfeifengesicht", which is a compound word that means "a face badly in need of a fist". Or a crowbar.

See also trollface, bitch slap, Umad? and Backpfeifengesicht.
"Yeah, I get it, that parkour was pretty cool. But stop giving me a doya-gao. It's getting on my nerves."
