The Golf Mug

It sounds like you're referring to a particular type of food or drink item that is commonly served in restaurants in the United States. After doing some research, I believe the "golf mug" you're thinking of is actually a popular menu item called a "Bloody Mary."

A Bloody Mary is a savory cocktail made with tomato juice, vodka, and various mix-ins such as celery, olives, and horseradish. It's typically served in a tall glass, often with a celery stalk garnish and a wedge of lemon or lime.

The name "Bloody Mary" is thought to have originated from the drink's blood-red color, which is reminiscent of the legendary Queen Mary I of England, who was known for her persecution of Protestants and earned the nickname "Bloody Mary."

Bloody Marys are a popular brunch cocktail in the United States, and they're often served in restaurants and bars, especially on weekends. Some variations of the drink also include additional ingredients like spices, hot sauce, or other mix-ins to give it a unique flavor.

I hope that helps you learn more about this tasty drink! Do you have any other questions about it?
