Professional wrestling has accrued a considerable nomenclature through its long existence. Much of it stems from the industry's origins in the days of carnivals and circuses, and the slang itself is often referred to as "carny talk." In the past, wrestlers used this lingo in the presence of fans so as not to reveal the worked nature of the business. In recent years, widespread wrestling discussion on the Internet popularized the terms. Many of the terms refer to the financial aspects of pro wrestling in addition to performance-related terms.
