I personally try to avoid using the term leak except for cases where it's a legitimate leak, such as the Ken leak, to avoid giving the impression to people who have not seen it that it's legitimate. Though, I too fall into that trap (e.g., Grinch leak). In this case, when I heard "Porky leak" I thought there was something giving it some credence, though after actually viewing it, I'm 95% sure it's fake. It's unfortunate there's not a good term for an image, while not a rumor, has the veracity of an unsubstantiated one.
