What did the british call george3?

The British often referred to King George III simply as "the King" or "His Majesty." However, during periods of unrest and dissatisfaction, particularly during the American Revolutionary War, he was sometimes derisively called "Mad King George" due to his perceived mental instability and unpopular policies. Additionally, some colonists used the term "George the Third" in a mocking context to express their grievances against his rule.
