I liked it when one of the 'nice' personality villagers started calling me "Cookie" ^^ Because thats my cats name. But come to think of it I cant remember if that was in New Leaf or Wild World
really early in my current town, Coco gave me the nickname of L-puff, and i liked that a lot. later, Stitches gave me the name of Belle L, and i liked that as well. L-puff is still my favorite
Right now, Grizzly is calling me "june bug" and I think that's pretty cute. I've also had villagers call me regular nicknames like "sweetie" and "honey" and I think those are nice, too. I'm also kind of partial to LadyD and BelleD.
Sweet-P!! it just sounds so cute and i am forever grateful to rosie for thinking that up <3 also not a nickname but at one point when kabuki recommended a pwp to me he called me "mayoroni" and i found it really funny so i told one of my villagers to call me that and it spread ))
cupcake and muffin are classic ones that always make my heart all gooey and warm my very first town bunnie called me muffin and in my current main town i think it was molly that named me cupcake :')
