the unglamorous hero covering everything you forgot to bring inside before the storm.
means A heavy, waterproofed sheet of canvas or plastic used to cover and protect things from rain, sun, and weather.
from A blend of 'tar' and 'palling' (from 'pall,' a cloth covering, ultimately from Latin 'pallium,' a cloak) — because early versions were literally canvas smeared with tar to make it water-resistant. Sailors knew it well, and the word even gave us the old nickname 'Jack Tar' for a seaman, since they handled these tarred sheets daily.
