Interpretarian

Interpretarian is a mutogender in which someone's gender is interpeted differently by another individual. They may have their own interpretation of their own gender, but they also identify as whatever the other individual interprets them as.

Examples include: - Person X identifies as a woman. Person Y perceives X as a man. Person X now identifies as a man.

- If person X is with multiple people with different perceptions, X may identify with all these genders, or may pick one.
