From the social justice stance, cultural appropriation is when a person sees something that someone else is wearing, creating, listening to, saying, etc and becomes so delighted and/or inspired by it that they begin to make it a part of who they are; although that fashion, art, or dialect happens to originate in a different geographic location, or is more commonly associated with people with a different skin color.

Basically it’s another non-issue created by first world privileged idiots that want a reason to complain about something, and/or pretend to be victimized.
