Well, this is kinda silly but my friends refer to me as "papadaca" (PAH-Puh-Dah-Kuh) in reference to my last name. It's kinda become my thing at school.
my name on everyone's snapchat is "ramen" so people just call me that now. although my nickname in a group chat is "legs for days" so i guess that counts too lol
But inrl, i've been called so many nicknames it's unreal how many things you can do with my name. People have called me Bec, Becks, Bex, Becca, Becky or simply the letter B. It's a surprise I don't forget what my real name is, because my mum always calls me by my nickname.
Most people just call me by my second name in a way where it's basically a nickname, which I really dislike, but my best friend has the exact same first and middle name as me (so neither are really a good alternative to use), there's about 6 other people with my name I see regularly and I work with about 5 others too.
I dislike it, but I also realize it's convenient for everybody including myself, so whatever.
People I've met online first tend to default to calling me Tao or Kit depending on which I was using at the time even when they know my real name, I would guess because that's what they knew me as first. My best friend absentmindedly calls me Tao occasionally, which is weird since he does stop talking and say in confusion "why did I call you Tao?".
I don't really mind this, though it's kinda weird when people IRL start referring to me by my online name(s). I just don't expect it.
Soooo many. My name is Katherine, so Kaydee is a nickname. I also get Kate, Tate, Kathy(which I hate), Kitty, Tatie-Tot, Bug, Pumpkin, Wendy, Katy-bug, Katydid, Ranga, Ginger, and Jade.
Now that's not even including the pet names from my boyfriend cause that list is too long.
