Pronounced with an extra long 'nnnnn' to prevent unnecessary confusion, this term is used to refer to a friend or acquiantance who knows about drugs. Any type of drug. Why the gov'ment is
corrupt and should legalise them. Which you should
stick in your eyes. Which you should stick in
your rectum. And so on.
Person A: Dude, smoking weed is boring, can we stick it in our
eyeballs?
Person B: Don't know man, you better ask Joe, he's the
Mann.
Person A: The man?
Person B: No, the
MANN.
Person A: Joe, can we stick weed in our eyes?
Joe:
By all means, but it won't get you high. Not a bit. Fancy a joint?
Person A: Thanks Joe, you're the Mann.
Joe: I know, man.
