There's a commedian who has a bit in a routine about the word "dude" He claims the it is the only word you need, because it can mean anything based on how you say it
(this won't translate well on paper, but...)
How's it going? -- Dude.?
Check her out! -- Duude!!
is an ax murderer in the closet? -- ...dude?
