Facebook name syndrome
You use someone’s Facebook name instead of their real name because you're too lazy to remember their actual name. It’s like you’re being a bumbling idiot who only knows them through a screen.

My dog’s Facebook name is @DogLover123 and he hates me.
I told my boss I was @ChillKid and he said I was fired.
