Professional wrestling has accrued a considerable amount of jargon throughout its existence. Much of it stems from the industry's origins in the days of carnivals and circuses. In the past, professional wrestlers used such terms in the presence of fans so as not to reveal the worked nature of the business. Into the 21st century, widespread discussion on the Internet has popularized these terms. Many of the terms refer to the financial aspects of professional wrestling in addition to in-ring terms.

Kazuchika Okada is a Japanese professional wrestler.
