ENA comes from the surreal animated web series of the same name created by Peruvian animator Joel G, which began online in 2020. The character shifts between cheerful and distressed moods, making her exaggerated lines easy to clip as reactions. This oh no no and bleh moment spread in short edits and soundboards because it compresses panic, disgust and resignation into four seconds. It remains popular for meme videos where a creator needs an instant horrified rejection that viewers recognise even without knowing the original episode or its strange dreamlike plot.
