Not cosplay, but I did try to explain to my mom what Gangnam style was. I think we both ended up more confused than when I started XD
Though I do remember this one time:
My mom: Did you hang that stuff up in your closet
Me: right next to the skeleton!
Me: Yeah, I have a literal skeleton in my closet
Mom: Why am I not surprised?
Me:...it's a prop!
Mom: I don't doubt that
Me: It has a name!
Mom: Again, not surprised. I do not care to know what that is though.
Me: *mumbling* you're so mean to my wife.
