When you are sitting at a table, maybe you have a hand, maybe you don't, but when the flop comes, the moron next to you says, "Damnit, I knew I should've called". That is the most destructive form of bad etiquette you can show. Not only are you being a crybaby, you are also giving information to all of the players who are still in the hand.
