Top definition
A person whose sexual orientation switches between homosexual and heterosexual, with each phase lasting from months to years. This may optionally be accompanied by partial amnesia in which the person insists they have always been their current sexual orientation and just did not realize it.
"So, did you hear that Alyssa has come out as a lesbian?" "Seriously? She dated Gerry for years! I had hunch she'd turn out to be a bi-canthrope. How long do you think it'll take for her to decide this has been a phase?"
