That's apocryphal. The term is originally Greek: barbaroi. It basically meant anyone not a Greek. It's a word that roughly translates to "non-citizen". Source: my Greek classical studies class in university.I don't remember where I'd read it but something along the lines that, to Romans, all the foreign languages just sounded like they were saying 'bar bar bar barbarbar bar' - which always makes me imagine Muppets.
