"Duuuude!" is a radically different from the word "Dude," which generally means someone of high charisma, and it, in fact, can used in lieu of nearly any word with three syllables or less. For example:
"Duuuude! Like, duuuude!" instead of "Wow, like, impressive!" Or, translated less directly, "Duuuude! That duuuude's got a duuuude!" instead of "I am thoroughly disgusted by the texture of this Key Lime Pie."
