Originally, the initials CM in his ring name represented the phrase "Chick Magnet", the name of the tag team he was in as a backyard wrestler.[4][12] Punk, however, later changed CM into an orphan initialism, declaring that it has no meaning,[5] though when asked since he has taken to making up meanings that fit the initials, going so far as to make up long stories to explain the origins that do not match the actual origin story at all.[5] Since beginning this practice, Punk has stated CM stands for "Cookie Monster",[159] "Cookie Master",[160] "Crooked Moonsault",[161] "Chuck Mosley",[161] "Charles Montgomery",[12] "Charles Manson",[12] "Crazy Mariachi", "Chicago Made",[162] "Championship Material" and "Cole Miner" among others.

Just saying. It has alot of meanings and none seem to be the true meaning.
