Hotter Than Two Squirrels in a Wool Sock

Origin

This blue phrase appears to be a modern creation that circulates online and in novelty "Southern" humor lists, but it isn’t found in older collections of authentic Southern or Appalachian sayings. Its odd image-two squirrels trapped in a wool sock-follows the same over-the-top pattern as real Southern heat expressions like "hotter’n blue blazes" or "hot as all get-out," but exaggerates the joke for shock value. It’s best understood as internet humor that borrows a Southern voice.

Verdict: Southernish. A modern exaggeration that sounds Southern but isn’t part of genuine Southern speech.
