The exact original recording behind this clip is not clearly documented, and it has circulated online mainly as a short meme sound rather than as a line from a widely known film or show. Search interest around phrases like try to relax your anus shows people find it through meme edits, DJ-style mixes and reaction videos, where the blunt wording itself becomes the joke. Its short length makes it easy to reuse, and its continued use comes from that shock value combined with a relaxed delivery that fits pranks, ironic edits and light-hearted roasts.
