The line comes from a fan-made YouTube parody in the 'if Deltarune was realistic' series, which reimagines Toby Fox's role-playing game with live-action-style logic and deadpan humour. Short voice moments from these videos circulate as meme sounds because they are easy to lift out of context and drop over unrelated footage. This greeting stuck around thanks to its warm, welcoming tone, and editors now use it far beyond Deltarune content, anywhere a cheerful arrival line fits.
