Reminds me of a bit of standup comedy I once saw. The guy said the most expressive word in the English language was the word "Dude", because of all the things it could mean with just a change of tone and inflection.
(now let's see if I can comunicate this joke in text)
It can mean, you just did really well. "Dude!"
It can mean, you just screwed-up really badly. "Dude."
It can mean, are you in the closet waiting to kill me with an axe? "Dude?"
