GBF

Brett: Why did you say that shit to Bec. You know it had nothing to do to you.

Harry: I swear I didn't say anything. You shouldn't treat girls like that anyway.

Brett: Your never going to be anything more than a GBF.

GBF
Generic Blonde Female. i.e. fit for purpose, but copies her looks from a magazine, and is devoid of any distinguishing features like a personality. Nothing to write home about. The opposite of "exotic", or "striking".
Nothing doing in the place. Just GBFs that left me hankering for some crazed goth bunny-boiler ...anything INTERESTING.
