Because the title is just a common lyric phrase, this short clip circulates online less as a full song excerpt and more as a standalone reaction hook. Short sung lines like this spread on soundboards and in short form edits because they are instantly readable, easy to trim to a few seconds, and work without any visual context. It has stayed in use as a quick optimism cue for predictions, plans and reveals, where creators need the audience to expect a good outcome before the next shot confirms it or undercuts it for comedy.
