A reference to JC (Julius Caesar) and "the boys" (Cassius, Brutus, Antony, Octavius, Casca, Flavius, Cicero, Lepidus, Murellus, and Decius). Commonly used by an English teacher named Harris.
JC and the boys had a nice swing'n'stab ballet in the closing Act of Julius Caesar because Cassius betrayed the honorable, noble Brutus before the unwritten act where Brutus plied his wife with 30 glasses of wine and had some fun with the boys. Damn you Cassius; if only the story would have gone on a bit longer, things would have gotten a lot better.
