Basically, if you didn't know already, Pirate King Luffy is referring to Luffy. Wanji is for Sanji, Grandmaster is for Zoro, so my question is that, when you see Sanjitards, Zorotards and Luffytards use those wank terms to label their favourite drawing do you just want to get up and shove some grass into those guys' face for being a bunch of fucking weebs who have never before touched any grass in their life? Definitely not me. I personally don't mind fanfic terms or overwank for certain charcters as long as it doesn't end in the fans shipping said character with themselves. But some people do so that's why I'm making this thread. So the question are, which term is more cringey and should be banned instead? About the origins of the slang terms, at least I understands about Luffy being called "Pirate King Luffy" because he's going to be the Pirate King (duh) and ''Wanji'' is pretty obvious too but I don't understand where people got the term "Grandmaster Zoro" to label Zoro. Like am I missing something here? I don't recall anybody calling Zoro "Grandmaster" or something along those lines in the manga. Well same for Luffy I guess because he's not yet the Pirate King.
If anything, Mihawk should be referred as "Grandmaster" since he's literally Zoro's master himself. What do you guys think?
