Text says ビッチ, which is "bitch". "Bitch" in Japanese can mean many things, like the English "bitch", or it can mean acting slutty, or being/looking offensive, or pushy, or hostile/mean, or being a tigress... It depends on the context. From the comment, I'm guessing it means someone who doesn't have the reserve/restraint/modesty/shyness of a traditional Japanese woman.
