Just to let you know, if you're wondering who is downvoting you, it's me. This comment and the one before were both stupid and unnecessary.
If you really gave half a shit about the original poster and the situation she's in, you wouldn't be going through picking on every damn comment and responding with idiocy, and starting branches of discussion that aren't relevant to the subject at hand and do nothing more than make finding useful information here more cumbersome.
Age doesn't have much to do with gender. If she was male I would have called her "The Django Guy". There's not a great corresponding female version of guy - chick sounds chauvinist, lady sounds to formal (think of how "The Django Gentleman" would sound). "The Django Woman" doesn't work either. What would you have said?
More choices from Encarta Thesaurus: lass, miss, young woman, mademoiselle, daughter, lassie, mademoiselle, maiden, damsel, maid, young lady.
"Girl" doesn't imply age any more than "dude" does, but it does imply a bit of disrespect over, say, "this Django coder", in exactly the same way that "this Django dude" would.
In the great tradition of Dear Abbey, I reserve the right to show a tiny bit of disrespect when told a tale of exploitation like the one the OP shared.
