The title uses the Mandarin transliteration ga zhua for a cockroach and quotes the exact vocal sounds in the clip, wu, e and e ah, which explains the slug and why the page is shared as a reaction rather than a song or dialogue line. Without a confirmed source recording, the sound circulates online purely on its performance, passed between short edits as a shorthand for disgust and panic. Its brevity keeps it reusable, so creators can loop the context around it while the scream stays recognisable.
