The term "maverick" has several meanings, but it generally refers to someone who is independent or unconventional in their thinking and behavior. It can also refer to an individual who refuses to conform to a group or party, or someone who takes an unusual or unorthodox approach to problem-solving. The term originated from Samuel Maverick, a Texas rancher who refused to brand his cattle, which led to the word being used to describe any independent thinker or doer.
