Tin het
From Super-wiki
A slightly ironic, usually derogatory term used by the most extreme wearers of Tin hats. It is used to refer to fans who believe that Jared and Jensen are actually heterosexual, and not in a relationship with each other.
Its use suggests that this belief is on equal footing with those who believe Jared and Jensen are in a secret relationship with each other.
Example: when a picture appears of Jared or Jensen is photographed with their girlfriends - "oh that will make the Tin hets happy".
