(Almost) Anytime someone calls my name, I spin to face them and say, "I didn't do it!" And there's also the more elaborate, "I didn't do it, and if I did, it wasn't that big of a deal, and if it was, I didn't mean it, and if I did, you deserved it!"
 
I react to my twin's name being called out because so many times IRL, people call me my sister's name that it has become my secondary.
 
Every parent (Mostly my mom, but whatever) does this:
(To me) "(Siblings name)! Uh, (Other siblings name)! No, AAAH what's your name!"
 
For me, my parents get messed up only when my back is turned. They learned to recognize my face, but yeah, they still call me my sister's name.
 
I... am not sure if I should laugh or say that's awful...
 
It's not awful, we really do look alike. Hell, when I got my last haircut, I remarked on how I see my sister in my reflection, and normally, I see me in my reflection. We usually varying hair lengths, my twin likes it short while I keep it longer, but I have shorter hair this time.
 
Ah, OK.
 
Oh and another thing, people always ask us "Are you twins?" when they see us together. Additionally, they keep thinking I'm younger than I actually am. I answered the door one time and the person asked if my parents were home, and another person asked if we're old enough to vote.
 
The twins problem seems to be a lot more common than one thinks. Some people, including me and parts of my relatives, had problems distinguishing my twin cousins.

To answer the question, I have hardly had any irl nicknames. I had one used by a small amount of people during high school, and one that only one person uses at work, but everyone else uses my real name.
 
I have this interest in digging. I dig with a shovel 90% of the time I'm outside. And when I am at my grandparents. My grandfather like to tell jokes that only I can understand. And the jokes I tell he only understands. I just can't seem to get enough of either.
 
I do this thing when I'm listening to an audio book, if it goes like, "Harry grimaced at this thought." or, "He raised his arms in alarm." I'll make a face, or raise my hands verrrrrry slightly, or whatever else it says the characters do.
