“Top banana” is a slang popularly used when referring to the most important person in an organization or activity. For example, the United States president can be referred to as the nation’s “Top Banana.” This slang originated in the American Theater in the early years of the Twentieth century. For example, the leading comic performer in a burlesque play was dubbed “top banana.” There were stages such as “third banana,” “second banana,” and “first banana” or “top banana.”
