"Dude" has also had an impressive run
My favorite Uncle, now deceased, used that term way back in the late 50's and he used it the same way people still do.
I don't recall anyone else using it until maybe the movie "Fast Times at Ridgemont High".
I had a guy from England on my crew back around 1993 who used the term "sweet". I had never heard it before but within a couple of years it was popular.
