I made a new character to spite biphobes.
His name is Bihet, he’s an ancient demon known for taking many wives, but never quite settling down with any of them. Over time, he became attached to bisexual humans, as he’s also bisexual, and so he began to favor and watch over them.
Now whenever a biphobe calls a bisexual person in an opposite sex relationship a “bihet,” he curses them.
(His kids and ex-wives all support him and his crusade against biphobes.)
