In those rare times I use the word “dude”, it’s invariably meant as an insult, as in “Dude, aren’t you a little behind the learning curve to be calling Saul Alinsky kind of a “cool guy”, when you’re SIXTY FRIGGIN YEARS OLD, AND JUST STARTED PAYING ATTENTION TO POLITICS WHEN OBAMA GOT ELECTED???”
Yes I see the word “dude” as an insult too. The term “duded out” means someone who is dressed like a cowboy in boots, hat and spurs but has never set foot on a ranch.
