Nerdle = a NON-SEXY female nerd. A SEXY & petite female nerd is a "
Nerdette". If she has big tits and a big hips (but NOT big anywhere else) she is a "
Nerdess" (ner-DESS, ie, Nerd/goddess).
I'd never go out with Gertrude; she's a nerdle. Now, her sister
Vanna, on the other hand, I'd love to go out with her, but, she is a
Nerdette, and
I just am not smart enough to impress her.
