In every community for every series, there are common mistakes. Someone could use the wrong romanization of a character's name, or think that the title referred to the main character, or insist on spreading a rumor about the plot until everyone believes it. See Also: Cowboy Bebop at His Computer, Fandom Heresy, I Am Not Shazam, Internet Backdraft, and Refrain From Assuming. An in-media equivalent would be Insistent Terminology.
