COLUMBUS (WCMH) — Ohio Governor John Kasich has once again declared a “scarlet letter Saturday,” ahead of this weekend’s football game between rivals Ohio State and Michigan.

Friday, Kasich tweeted what he called a “psa.”

It showed an official-looking resolution urging all Ohioans to avoid using what he called “The alphabet’s unlucky 13th letter” — which is “M.”

Each letter “M” in the resolution had been turned red and crossed out with a red line; A reference to Ohio State’s colors, which are scarlet and grey.

A lot of “M”s have been missing from twitter lately with Buckeyes fans dropping the letter from their tweets, including their own names.

The Buckeyes face off against the TTUN at noon on Saturday.
