My mother's side is all white trash and my dads side is Italian but not eurotrash. They are that hard working immigrant type. My husband's family is society descended from landed gentry aristos in England. Not nobs, unfortunately but gentry. They don't much care for me, but I know how to behave like a lady and the white trash comes out only sometimes.
I've dated both American white trash and a few Euro trash and the differences to me are that Euro trash guys smell better and dress better and go to a lot of effort to make people think they aren't. Also Euro trash usually has ways of getting money or has more on hand than white trash redneck boys do. Euro guys tend to really believe that they are more than they are or have opportunities that they don't have while white trash American boys know how to pretend it but don't really believe it.
If I was young and single I'd rather casually date a Euro trash guy cause they know how to act in public and know what's nice and what's tacky, American white trash does not usually without going to the effort to learn it. My mother went to that effort AMD made sure that even though I came from it,I didn't act it all the time.
Euro trash boys will roll the sleeves up on their expensive (usually obtained by some sort of can or theft) silk button down just to the elbows and then only when having to do something like change the tire on the girls car they are driving or looking for a vein to shoot dope in. American white trash will immediately roll up the sleeves on their WalMart button down shirt above the elbows and then push them up the moment they put it on. Eurotrash guys will wear nice jeans or pants AMD expensive shoes with it and even nice socks. American white trash will wear their tennis shoes or work boots with dress pants even though their mothers bought them good shoes to wear. My sons picked up a lot of the white trash redneck traits from living in this town and also because they are bloodline makes them prone to it. Although they aren't so much trashy by blood because they only have 1/4 real white trash blood. But we live in redneck central.
Not all rednecks are white trash and not all white trash are rednecks. But all crackers are white trash. Also American white trash, like rednecks, believe that a ball cap is appropriate in almost every place they go and will wear it. They also tend to call every other man "boss" or "bossman". Spider web tats on the elbow is another outward sign of American white trash, as is willingness to fight over the honor of their favorite band, wrestler, or even, yes, football team.
Eurotrash is much sneakier than American white trash, mainly because many Americans don't know all that much about Europe and many have a willingness to believe that the Eurotrash guy is some uncrowned or deposed royalty or disgraced nobility. If a Eurotrash guy finds the right American white trash girl whose family has acquired a little bit of money and she has access to it he will think he's in heaven. I learned quickly, but someone clued me in. So I dated the guy and enjoyed myself but never gave him money and guarded everything I had like a German shepherd. He was much more fun to date than American white trash.
And trash doesn't mean you're garbage. It's just a term to describe those at the bottom of the social ladder.
