Shiteyanyo is a bizarre and surreal derivative of the popular Vocaloid character Hatsune Miku, characterized by her head being attached to two twin-tails that function as legs. First appearing on Pixiv in 2010 by artist deino, the character quickly gained 'cursed' status within the Hatsune Miku community due to its unsettling yet humorous gait and anatomy. The name itself is a play on 'Shite yan yo' (I'll do it). Shiteyanyo is typically used in memes to represent something unsettling, weird, or aggressively persistent, often depicted walking towards the viewer in a threatening or comedic manner.
