Masonism 

The practice of conducting an unfair or prejudiced trial; the instigation of a show-trial conducted by a biased quasi-judicial nincompoop.

Sarah was unfairly treated - her disciplinary hearing was pure Masonism.

Mr. Masson 

A math teacher that coaches baseball, who talks very loudly (almost screams.) Gets off topic very easily. Knows drama more than students and reenacts fights infront of class. Favorite number is 13. Makes up own hand signals. Best teacher ever!

I wish I could be a Mr. Masson.
