The sound originates as the incoming call alert in the Snapchat app, heard when another user starts a voice or video call. As creators began screen recording conversations and staging fake calls for short videos, the ringtone moved beyond the app and became a recognisable meme cue on its own. Its meaning is understood instantly by regular Snapchat users, so editors can set up a prank, a surprise call or an interruption without showing much context. That clarity and its looping rhythm keep it popular for reaction edits and story style clips.
