This sound is best understood as a stock-style slime or splat effect rather than a quote tied to a specific character or scene. Clips like this spread through short-form edits, gaming montages and meme videos because they exaggerate impact without sounding violent. The reversed lead-in gives editors a built-in setup before the wet hit lands, which makes timing easy in fast cuts. It is still used because it reads instantly as messy, goofy and over-the-top, especially in reaction and fail content.
