Although there exist a number of threads focusing on certain components of those which generally characterize a bimbo e.g. slutty clothing, huge fake tits I have yet to locate a pure bimbo thread! So here goes... As I am the now self-proclaimed expert on bimbos I'll categorize them by their sub-species. Please, please feel free to add your own.
The first is the "Fuckdoll". The Fuckdoll is usually between 18-30 and this is her initiation into being a bimbo. She may not have fully completed the transformation (no fake tits yet) and might be still unsure as to what her role should be socially.
