Being that you’re relatively new to this forum-here’s the origin of ratter. A man now (if he is still among us) in his mid 70s who I knew in college used the term “that blows dead rats”. I used it as a descriptor of a winter event that went bad or perhaps a pattern-maybe you remember-it was before subforums and you’re one of the originals. Anyway, the term ratter stuck. Just as “storm cancel” is courtesy of blizzard24, ratter is from my college days 50-55 years ago.
Anyway, I had one beer and felt compelled to explain...lol.
