Just had one. My cosplay friends and I will call each other by our characters' names, even in public. My dad and I were driving back from McDonald's and my friend was walking to McDonald's so I roll down the window and shout "Hi KRYLANCELO!" to which she yells "Hi Hartia!" and I pull my head back in the car.
Dad: can't you just say hi [real name]?
me: no, that's how we talk to each other!
