An admitted dude-user during his college years, Scott Kiesling said the four-letter word has many uses: in greetings ("What's up, dude?"); as an exclamation ("Whoa, Dude!"); commiseration ("Dude, I'm so sorry."); to one-up someone ("That's so lame, dude."); as well as agreement, surprise and disgust ("Dude.").
Kiesling says in the fall edition of American Speech that the word derives its power from something he calls cool solidarity--an effortless kinship that's not too intimate.
