The origin of the phrase is not entirely clear, but it is thought to have originated in the world of sports. In the early 1900s, sportswriters began using the term "hero" to describe star athletes who excelled in their chosen sport. They also began using the term "goat" to describe players who performed poorly or made critical mistakes. Over time, the phrase "hero to goat" came to be used to describe any athlete who had experienced a significant decline in performance.
In recent years, the phrase "hero to goat" has also been used more broadly, to describe any person or thing that has experienced a similar fall from grace. For example, a politician who is once popular may become a "goat" if they are caught in a scandal. A company that is once successful may become a "goat" if it experiences financial difficulties. The phrase "hero to goat" is a reminder that even the most successful people or things can experience a sudden decline in fortunes.
