"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.

I had two great uncles who were brothers and growing up in the 1930s, they both called each other 'Dude.'

My Father said they were called the 'Dude Brothers' by their family and friends!
