I want to know the answer to the following question:
What is the popular way for wrestlers to refer to one another?
All the background I'm provided with is that "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.". Is that enough to answer the question?
