i am pretty sure it originates from futaba or nico nico douga because i would always see it posted in obscure otaku-y contexts
it's a single guy that's dressed in a red gi like ken from street fighter, with blond hair and prominent eyebrows on a blue backdrop, and he's making this stupid curious-interested duckface
the guy himself is like a comically shitty early 2000s cg character (think the original baki anime or jimmy neutron)
