Once apon a time, a young girl was far too fond of dying her hair.
One day, in yet another attempt to become a blonde (somebody told her they had more fun, and she had already been brunette, black, red, and various unnatural colours of the rainbow), after a losing battle with a bottle of bleach, the young girl's hair turned somewhat a shade of ginger.
The next day at college the young girl's best friend thought it would be highly amusing to stick a picture of Geri Halliwell to her locker, and hence the name 'Geri'. Where the 'Bimbo' part came from.... well, I'd like to dispute it but I'm not sure I'd win
