A single friend of mine asked me to look for a guy for her recently. I asked her what kind of a guy she wants and she says to me:
HE has to have a job - understandable
HE has to be good looking - understandable
HE CANT BE A FOB - confused 
Most fobs I know may have an accent but still have excellent grammar. They dont have any issues communicating or expressing themselves.
Is it that big of a deal???
