The Shield was a professional wrestling stable in WWE that consisted of Dean Ambrose, Roman Reigns, and Seth Rollins. Their original characters were mercenaries for CM Punk; however, they quickly became mainstay main-event names. The group debuted on November 18, 2012 at the Survivor Series pay-per-view. The Shield was a dominant force in six-man tag team matches with an undefeated televised streak lasting from December 2012 to May 2013, during which they scored a victory at WrestleMania 29. In May 2013 at Extreme Rules, all three members of The Shield won a championship, with Ambrose winning the United States Championship while Rollins and Reigns captured the WWE Tag Team Championship. Rollins and Reigns were WWE Tag Team Champions until October 2013, and Ambrose was United States Champion until May 2014, which was a record reign for the WWE version of the championship. As a Shield member, Reigns gained prominence by setting and equaling elimination records at the 2013 Survivor Series and the 2014 Royal Rumble events.

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.
