The 'I Feel Fantastic' meme originates from a cryptic YouTube video uploaded in 2009 featuring a mannequin-like android named Tara. Created by John Bergeron, the video shows Tara wearing different outfits and singing the phrase 'I feel fantastic' in a synthesized voice. Its eerie production triggered the 'uncanny valley' effect for viewers, leading to numerous creepypastas and urban legends. Today, the meme is used to represent feelings of artificial happiness, burnout, or a sense of existential dread masked by a polite exterior.
