In my family we tend to just say random things that fall out of our mouths and create nicknames that make little to no sense. So things that start with 'Little Miss' or end with 'girl' regardless of what came first or after is really annoying, and it still happens. My older sister doesn't get the same treatment, I get it because I'm the baby of the family. My parents used to take my birth name and add that '
ee' sound to the end of it which is really feminizing and babying. - This treatment however seems to be happen more now than ever.

Other than that I don't really know if my main nicknames were feminine, like
Munchkin....
When I was in school my sisters friends used to call me
Squirrel girl, this was because at the time my two front teeth had come in and I liked to bite people like some wild animal and climb trees, I remember I didn't hate the similarities I had with squirrels but I hated the name squirrel girl. But yeah, mostly people just called me
brat, or
Mickey/Mickey Mouse.
Oh a good friend of mines mom used to call me
Jane because of George of the jungle, I was kind of crazy like George, wild in fact, so rather than calling me George, they used the girls name, from what I remember though she wasn't all that wild, kind of prim and proper looking. Also my friends dad used to call me
little boy. - He had no idea how happy I was every time he did that. And he said it on almost a daily basis! I remember trying to even sound offended but I would smile so hard and my day would just be set in the right direction, so I couldn't even pretend I felt any other way. I never liked the name
Michael but the one or two times he said it, it felt a lot better than my birth name and calling me a boy all the time was just icing on the cake as a carefree child! Oh and he'd also ask "Who's that boy?" All the time while looking at me.

I freaking miss him, and I even miss my friends mom, more so than I even miss that friend!
