PPB (Professional Polite Bitch)

A PPB is a professional polite bitch. Someone who comes off as polite and professional, but also has a condescending and rude attitude/demeanor.

This customer service representative I spoke with really did not care about my situation, but she was definitely a PPB (Professional Polite Bitch). Props to her for holding up.

I tend to be a PPB at work, I am nice enough so I am not fired but bitchy enough so people know I don't care.
