With no widely documented source attached to this short clip, its appeal online comes from the title itself, which instantly suggests a private ritual between friends. Short soundboard clips like this travel through memes, edits and reaction videos, where a recognisable label matters more than a famous origin. Creators reuse it because the phrase secret handshakes is easy to visualise and easy to pair with greetings, pranks and team introductions. That flexibility keeps it useful for quick, shareable moments, even without a single film, show or viral video behind it.
