noun: A pedestrian route chosen for its warmth, rather than because it makes the pedestrian's trip shorter.

Warmcuts can be taken in an urban area, usually through a department store or office building that spans an entire city block, for the specific purpose of avoiding the cold weather outside.

On the way to my annual winter lunch with Pierpont, I took a warmcut through the County Services building.
