The new word has been coined for the growing number of straight women who flirt with bisexuality. It refers to people who have a sexual preference but refuse to be bound by it.

"Women are often more open to these experiences when they reach their 40s and are more confident with their sexuality. If an opportunity presents itself they may think "why not", particularly if they have come out of a long relationship," the Daily Mail quoted Psychologist Dr Cecelia D''Felice as saying.
