Article: An individual wrestler may sometimes use their real name, or a minor variation of it, for much of their career, such as Angelo Poffo, Ernie Ladd, Verne Gagne, Bret Hart, and Randy Orton. Others can keep one ring name for their entire career (cases in point include Chris Jericho, Shawn Michaels, CM Punk and Ricky Steamboat), or may change from time to time to better suit the demands of the audience or company. Sometimes a character is owned and trademarked by the company, forcing the wrestler to find a new one when they leave (although a simple typeset change, such as changing Rhyno to Rhino, can usually get around this), and sometimes a character is owned by the wrestler. Sometimes, a wrestler may change their legal name in order to obtain ownership of their ring name (examples include Andrew Martin and Warrior). Many wrestlers (such as The Rock and The Undertaker) are strongly identified with their character, even responding to the name in public or between friends. It's actually considered proper decorum for fellow wrestlers to refer to each other by their stage names/characters rather than their birth/legal names, unless otherwise introduced. A professional wrestling character's popularity can grow to the point that it makes appearances in other media (see Hulk Hogan and El Santo) or even give the performer enough visibility to enter politics (Antonio Inoki and Jesse Ventura, among others).

Question: What is the popular way for wrestlers to refer to one another?
Ans: by their stage names/characters
