Yesh~! I have a lot! =3
//one: Mari ~ It came from my dad's middle name and my mom's maiden name. [<~ not really my mom's maiden name 'cause I thought her maiden name was 'Maiden'. X3;] Anyhow, my friends gave it to me [see, they thought 'Maiden was my mom's maiden name, too. X3] and I <3 it! It ish my favorite nickname. :]]
//two: Francheese ~ My friends made it up...again. Since my first name ish Francesca, my friends thought Francheese would be cute. XD; I like it, not as much as Mari, though.
//three: Banana ~ My little cousins made this one. They thought of it because I wuv monkeys and because my middle name rhymes with it. I like it, too. It ish kawaii. X3
//four: Scieszka, just kidding, Chesca ~ From my first name again; my cousin gave me that nickname. She said my name was too long so she calls me that for short. I like it, I guess, but I really like the first spelling better. It ish unique and pwetty~! XD
