Simple lang...
[1] Just have basic knowledge about the game - the rules, the players, the teams. Google before every match.
[2] When someone yells "off-side," don't ask what that means. Just say "aah..."
[3] When someone scores, yell like everybody else does.
[4] Shout "good save" when the goalkeeper prevents the ball from entering the net.
[5] When a player goes down during a tackle, you can behave two ways...
a. You shout that it was muthafuckin dirty play
b. You shout that the fallen player was over-acting. Usually this happens with a "star player"
[6] Safest rule of all: just shut up, drink your beer, eat your pulutan, and watch the hot fan gurls. Those are the reasons you're watching the game anyway.
