This is a general slurping sound effect rather than a quote tied to one famous character or scene. Sounds like this spread widely through meme edits, short-form videos and prank audio because they instantly signal exaggerated sipping, licking or swallowing. Editors keep using them because the effect is simple, familiar and easy to sync with visual gags. It fits food jokes, awkward close-ups and gross-out humor, and it also shows up in reaction edits where a single wet mouth sound makes the moment funnier or more uncomfortable.
