Sexual Bipolar Disorder is a mental illness, one that causes a complete, drastic and random change of sexual preference overnight.

One day you're attracted to guys, and girls disgust you. The next you're attracted to girls, and guys disgust you. The day after you're attracted to squirrels, and humans disgust you, etc.

Omnisexual people often exhibit signs of sexual bipolar disorder.
Jim: "Geeze, look at Josh over there. Yesterday he was all interested in Jane, but today he's totally checking out that tree. What a freak."

Burt: "Woah hold on man, Josh is sick. He's suffering from sexual bipolar disorder"

Jim: "Oh, wow. I'm sorry that I insulted him, that sounds tough."
