Procrustean is an adjective that means enforcing conformity.
According to Greek mythology, Procrustes was a cruel villain who was eventually killed by the hero Theseus. Today the word is used to describe a villain who forces others to move in lock step to their command.
Mrs. Beale could be a procrustean leader in our sixth grade English class. She demanded that everybody adhere to her very strict dress code that included no short sleeves, no shorts, no colors except for those representing the Pittsburgh Steelers black and gold.
