I've got a few.
Most of my friends either call me Mimi
or Mel. Sometimes Melly on the rare chance, ehe. Some old friends call me Bucky/Buck. Sometimes I'm Cheemsy Meemsy. Or just, Meem. LOL. Still get called Seona but it's very rarely... but! I've got more > : )
Family wise? Got a few of those as well. My dad calls me Melmac (the planet ALF comes from), my mom calls me
Mahna Mahna (sometimes just one Mahna LOL (my father calls me Mahna, but it's not the double like my mom AHA)...
Ummm, little brother calls me Goonter/Goontie/Goontler/Goont... There is an explanation for this. I'm really good with nicknames and I tend to make them even better once I start using it. I started calling my little brother 'Jaygonts' (his name is Jason), then it just became Gont/Gontie. Then eventually we added an 'oooo' sound in it, and.. boom. We BOTH call each other Goont or some other variation. Very rarely do we call each other by our real names, unless if we're annoyed with one another, ehehe.
My second oldest sister calls me her Mini-Me, or Ree, as there was a time I went by Avery and she just calls me 'Ree'. Her and some of her friends do.
My oldest brother just calls me 'Mels-anie' (inserts an s into my name for some reason), and I think it's so cute lololol.
My oldest sister really doesn't call me much of anything. Sometimes Melmac, like my dad, but... I'm typically just 'bruh' x)
