The smoochin name comes from online soundboards where short kiss effects are filed under playful slang for kissing. This two second clip spread as a reusable reaction because it needs no dialogue or context to be understood. Editors keep returning to it for Valentine's edits, shipping memes and cringe comedy, where a real kiss would be too subtle and a written caption would slow the joke down. Its cartoon exaggeration has kept it useful long after many longer romantic sound effects fell out of rotation on short form video.
