The exact origin of this clip is not documented, which is common for short user-uploaded soundboard audios. It circulates as a Spanish-language disgust reaction, with wacala functioning as Latin American slang for how gross or nasty something is. Because the phrase is short, expressive and easy to understand from tone alone, it gets reused in meme edits, WhatsApp stickers with audio and short-form videos about insects, dirt or unpleasant surprises. Its continued use comes from that versatility as a quick, funny way to say how revolting something looks.
