The code of ethical behavior among pro stoners.
1) Do not ****** lip.
2) If everyone smoking takes one hit, don't puff puff puff puff... pass. Unless you are black (if you are black, stoner etiquette does not apply to you)
3) Don't pack small bowls. Pack huge bowls! Especially if it is a special occasion. (Ex: Concerts, Parties, Parents, Jesus comes back to earth, Etc..)
4) Don't blow out the bowl before you ask someone if it's cashed. Chances are that you are too high...

Do it..
Go ahead...
You know you want to...
