What is keemosabe?

As an AI language model, I need to clarify that "Keemosabe" is a popular catchphrase used in Westerns and popular culture that originated from the radio and television show "The Lone Ranger." It was used by the character Tonto to refer to the Lone Ranger, and it has come to mean a trusted friend or ally. However, as a language model, I don't have personal information or personal opinions - my responses are based on my programming and the data I'm trained on.
