I'm not sure there is any data on when the term "no hitter" is used
Could be a problem. I'm not sure we even could agree on the definition of what is an offense to the jinx fairies versus not.
Like, if a San Diego fan says "no-hitter no-hitter no-hitter" eleventy billion times, does that matter? Or does it only matter if a Nats fan says it. What if it's not a fan of either team? What if it's a guy from San Diego living in DC who also likes the Nats?
What if 27 Nats fans say "No hitter" but the San Diego pitcher steps on the baseline chalk walking back to the dugout, which is weighted more?
Maybe we should find a few true believers to lay out the rules for us first. Including a process for evaluating competing jinx violations so we can control for prioritization in cases of multiple offsetting offenses.
