Least Favorite Puppy circulates online as a short, shareable reaction clip rather than a widely documented meme with a single clear source. Its appeal comes from a simple, reusable setup: ranking something cute and then singling out one entry for a gentle roast. Creators reuse it in tier lists, reaction edits, and short-form videos because the phrase is instantly understood without extra context. That portability keeps it useful well beyond any one trend, especially in edits that need a fast, light-hearted verdict on a last-place pick.
