1) Originally, “dude” meant a stuck up person who dressed overly well. It first emerged in the year 1883 in England.

2) Later it was used in the old west to mean a city person who moved to the west without actually know what he was doing. Synonymous with “city-slicker

3) Later, in California, the term changed from these insults to a term meaning any male, human or otherwise. Sometimes it is used in reference to tom-girls. Now, it is often used for emphasis as well.
“Look at that rich fellow; what a dude! Do you see the feather in his hat?”

“What’s that dude doing in these parts? I bet he can't even ride a horse!”

“Hey dude, I missed you at the movies the other day!”

“Dude, that's harsh.”

A word meaning boy or young male figure. When used creatively, "dude" can also refer to a girl. This word is used at the beginning and/or end of sentences.
Dude, did you see that girl in the tight skirt back there?

Forget the fancy explanations for this. It simply replaces "man."
"Man it's hot." becomes: "Dude. It's hot"

"I failed my test. Man!" becomes: "I failed my test. Dude!"
