a horse named Charlie, had his leg spazz out, so every time someones leg spazzed people called it a Charlie Horse. Charlie was the laughing stock so he became a rogue horse.
Rob Horse: "Woh Sarah your leg is spazzing out like crazy!"
Sarah Horse: Guess I've got a Charlie Horse."
Sarah Horse: Guess I've got a Charlie Horse."
