I was referred to as a guido - FML!

I may have a blowout haircut, decent tan, and in very good shape, but I'm far from a guido.....far from those douchebags on Jersey Shore. Yet I walked into a gas station today in South Philly and heard some chick say to her friend "look at that guido over there, trying to be like the situation" or some sh*% like that. I'm an engineer and I'm in a committed relationship with my girl, I'll be damned if people call me a guido? FML, it sucks that people still judge a book by it's cover. But hey, let this be the worst thing that happens to me. Still, it p*ss*s me off.
