Here are only two rulez in this honorable club.
1.) You have to drink every alkohol with your left hand.
2.) When another honorable Buffalo Club member spot you drinking alkohol with your right hand, he is forced shout you a BUFFALO
In this case, you have to drink your alkoholic drink at once. (under the loud shouting "Buffalo, Buffalo, Buffalo...)
If you have been called a Buffalo by drinking a non-alkholic drink - or the other guy was simply wrong (left and right becomes more difficult related to your own count of drinks) THANNNN the guy who shout you a Buffalo have to drink his drink at once.
Third:
once a buffalo - always a buffalo
