The Supreme Court on Wednesday will hear a case pitting a foul-mouthed cheerleader against a censorious school administration, with possibly wide-reaching First Amendment implications.

The case came out of a typical high school incident. In May 2017, Brandi Levy, then a sophomore in Pennsylvania, tried out for the varsity cheer squad and failed to make the team. She was disappointed and posted on Snapchat, “F— school f— softball f— cheer f— everything.” She, however, had made the junior varsity cheer squad. When the school caught wind of her social media post, it banned her from cheerleading for a year.
