For a while every single villager was calling me cleats, except for Octavian who was calling me Brainiac. Now Wonder L is slowly spreading among them all, except for Octavian who is still calling me Brainiac. This is the sort of thing that happens when you say: "Yeah, sure" to everything your villagers suggest.
I actually made my own OC's in Animal Crossing New Leaf. I named my mayor 'The Witch' after a character of mine, and his husband 'The Dr'. It's a long time roleplay with a friend ^^;. Anyway, his actual name is Pierce. I kind of regret not just naming him that to begin with, but oh well. That's kind of his alias hes known by later on anyway .
However, I did eventually get to the status of friendship where some of the villagers have decided to nickname me. At first, they wanted to call my guy 'Mr T' or whatever, but I said no. I made them all call him Pierce. They keep trying to change my nickname though to 'Dr T' or 'Mr T' or something 'hip and fresh' or whatever. It's kind of annoying but cute at the same time.
With my other characters in Boy Love, I do not care... Though I don't think I play on them enough to actually get the animals to refer to them as nicknames anyway. At least, they've never been nicknamed/approach. Who knows, maybe the animals have secret names for us behind our backs? XD
For some reason in my town *before I reset it* everyone jumped on the "Honeybun" bandwagon! lol I think Chief started it, and then all the others wanted to call me that too. It was weird. lol
