parob
A physically working peasant (mid-age Europe), word comes from Polish 'parób'. Parob had to work for his lord before he could work on his own acre (his work for lord was called a corvee). Nowadays often used to offend someone, to suggest that he is not important in our hierarchy.
He thinks he rules. In fact he is just a fuc**g parob and has to work out a corvee on my acre.
