Unlike clips taken from a film or television show, this lemon sound has no single famous origin, and it is best understood as a generic kitchen and cartoon sound effect that circulates on soundboards. Similar lemon squeeze sounds have long been used in comedy, cooking content and animation to suggest sourness without dialogue, because the wet, sharp noise is instantly recognisable out of context. On short-form video and meme pages it is reused for sour-face reactions, food challenges and playful pranks, where one squelch can carry the joke.
