twincest

Incestual love or actions between twins, usually identical.
People have said twincest is like masturbating, because it's like having sex with yourself, but it's not. When you masturbate, you have sex with your hand, not another person who looks like you. They are two completely different things.

Girl 1: Omg I totally ship Chandler and Christian!
Girl 2: Uh...but they're twin brothers... That's disgusting.
Girl 1: No it's not! It's twincest!
