I made everyone call me Ant because that's what my friends keep calling me. Except for Mira, she thought of A-train and I thought it was punny. I'm a train.
Pietro came up with chickpea and it's spreading like wildfire, usually I get nicknames based around using the letter D so I'm glad to have a nickname like that for once
Fauna and Wolfgang are calling me lamb now. which I find pretty funny. x0D everyone else is still calling me Robo J. I loved that Wonder J nickname Walker gave me a while back.
My current village nicknames are "Li'l B", "cupcake", and "squishy".
The last one is self-chosen when given an input option, not freely given by one of my villagers. In the past, one of my favorite villager-given nicknames was "honey", but I haven't been called that in months.
In Keydrake I'm called "cookie" by some of my villagers and "cupcake" by the others! I've considered changing my nickname to "cpt. potato" or something, though, for the giggles. X'D
