What do they mean by 'hey dude?

Answer 1

"Hey dude" means "what's up" or "hello friend" (to be more precise). It's just something some people say to their friends or when approaching someone else. it's a slang term for "hello". A dude was what the cowboys in the American Old West called an Easterner, especially if he was over-dressed and "fancy" looking. A dude was once an insult, but over the years, it came to mean any well-dressed man. Surfers in California took up the phrase, and used it to refer to any male. dude also means hair on an elephants butt. ha! -sammi
