polygamadioecious 

Of unstable sexual orientation. Usually a botanical term used to describe a plant that can be either male or female, but can be used to describe a persons sexual instability. Used to describe people who prefer both men and/or women, but change their mind on a daily basis.

Not often used by everyday people, only by those who crave attention from their peers and want to appear clever.
