Little is documented about the original SkullStream upload beyond its Snapchat association in the title, so its history is mainly an online one. The clip circulated as a short soundboard file named for Snapchat, where skull emoji reactions are a common shorthand for stunned or amused disbelief. As short form editing grew, creators reused the same brief hit across chats, streams and meme compilations because it needs no context to understand. Its small file length and instant payoff keep it useful for reaction edits where timing matters more than a longer musical cue.
