Very little is known about the original recording behind Peggy X Slass, and the name appears to come from a user uploaded soundboard title rather than an official release. Clips like this spread because of their length and timing, getting reused across meme edits, Discord soundboards, and short videos where creators need a one second punctuation sound. Its popularity comes from utility rather than a known source, functioning as a generic abrupt stop that fits almost any fail or surprise moment without needing context.
