Ok, if I say the next few words and you don't know the answer, either 1) you drank way too much and have no brain cells left, or 2). You never went to the bar while at the camp. Actually we even played it in the camp so this should really be the anthem of the 1986 campo italia.
What's the name of the game?
Thumper
Why do you play?
To get fucked up!
Here are the rules of how to play in case you forgot.
You need: people and drinks

First everyone must think of a hand gesture. That is your "sign". Go once around the group and everyone demonstrates their sign. It can be anything you want, but it should be simple and fast to do. Then one person starts the round. Everyone drums on the table or ground with their hands throughout the whole game. The leader says "what's the name of the game?" continue drumming and yell "thumper". The leader then says, "Why do you play?" and the group yells back "To get fucked up." Once that is said, the leader makes his own gesture and then the gesture of one of the other players. The person whose sign was made must then make his own gesture and then someone elses. If you make a mistake, you have to drink and then you are the leader. Remember first make your own sign then someone elses.

I don't know who started this, Leslie (USA) was it you?You are right there in the picture, explaining it all! Gottcha! Anyway, it was a big hit at the Ponte Vecchio bar/pizzeria. We had the owners playing and I think we got a lot of free food/beverages because of this game.
Guido (Germnay) was nice enough to supply some pictures of people playing Thumper at the Ponte Vecchio bar. Great shots, Guido. Thanks. Anyone have any Thumper stories? Or Thumper pictures. post them here please!
