A person of flexible sexual orientation. Whereas they flirt with and try to attract both sexes, yet refuses to identify as bisexual. This person will constantly alter which gender they are more attracted to. Often they will appear to be very androgynous, and hang out with the scene crowd.
"Dude, Is David kissing a guy? I thought he was straight."

"Nah, he's flexisexual. Give him an hour, he'll be hitting up some girl, and in 4 he'll be 'sleeping' with the guy."
