The sound comes from a Vine posted by Nicholas Fraser in 2015, in which he sings the line while questioning someone who keeps lying. The clip spread quickly across Vine, YouTube and later TikTok, where creators reused the audio over reaction videos, pranks and everyday exaggerations. Its short length and memorable melody made it easy to reuse, and it remains popular because calling out a lie is a familiar, relatable moment in comedy and online conversation.
