Thin privilege is the word cacomorphobia. That is the “scientific” term for an irrational fear of fat people.

The problem with this term is that the prefix “caco” does not mean “fat”. It means “ugly.”

[mod note: Or bad, or evil. And “morph” refers to shape. Fear of the evil or ugly shape. Yep, that’s thin privilege, all right. Stinks, doesn’t it? -MG]
