Usually when someone calls me a fish, it is because I have their chips and they are pissed. Seriously I love it when someone bets too low and gives you odds to call a draw, and then when you hit, they get all jacked and start calling you a fish. I used to like to wind them up more by saying 'Yes I am a donk...a donk with your chips.' Or 'you know what a definition of a donk is...a superior player'
