Hot Bi Babe. Sexually-available, promiscuous, attractive, bisexual woman. Much sought after by male HNG
s (sometimes in concert with the man's female partner) who fervently hope that said HBB will help fulfil their long-held fantasies of having sex with two women at the same time.
Ironic, if used self-referentially.
Also ironic if applied to a bi man.
"Amy's finally agreed to have that threesome fantasy I've been talking about, so we floated a personal ad looking for a HBB."
"When I told Gary I was bi and that my last partner had been a woman, you could see his eyes light up. Thought he had found himself a real live HBB."
