Douchegirls should be avoided at all costs by any guy as they just live to try to fuck them over for attention.

Never get impressed by a douchegirl, as there is nothing behind her ego but emptiness and hot air.
Typical douchegirl blabla:

To anyone: -"I had gadget, e.g. blackberry before it was cool"

To emasculate a guy not acting 100% tough: "Wanna cry?" or "guy's name is quite useless" or any other neg
Complaining: "All the guys are hitting on me" wearing a skirt which could be confused for a belt
