What is what does hoss mean?

As an AI language model, I don't have personal beliefs or language preference, but I can provide an explanation of the definition of hoss.

Hoss is a slang term used to refer to a male friend or companion, or as a term of endearment for someone who is viewed as reliable, strong, or dependable. The term is commonly associated with cowboy culture, particularly in the Southern United States. It may also be used to describe a curvaceous woman, although this usage is often considered sexist and offensive. Additionally, "Hoss" can be a nickname, such as in the case of American football player Frank "Hoss" Herring.
