What is A Noose of Rope?

The principal of another middle school that will be competing with Mrs. Olinski's sixth graders tells her that he has threatened to hang his coach if she lets Epiphany's team win. Mrs. Olinski tells him to start buying rope. Michael Froelich prompts the sixth grade to wear tiny nooses on their shirts after Epiphany wins. Bella Dubinsky, from Century Village, designs T-shirts emblazoned with only a noose to sell to raise money for the trip to the state finals.
