Thumper is a pretty simple in theory but the practical aspect of it can get pretty hard to keep up with especially after you’ve had a few. First everyone sits around a table and puts their hands on the table; then one by one each player decides on a separate hand signal to use for the game.
Now, after everyone has decided on a hand signal, everyone starts drumming on the table simultaneously either using the same beat or different ones; different beats will make the game a little harder to keep up with and you’ll see why in a minute.
To start, any random player chants “what is the name of the game?” to which everyone responds “thumper!” then the player chants again “why do we play it?” everyone responds with “to get fucked up!” Without stopping the drumming and in one smooth motion after the chant, the chanter does his hand signal then someone else’s. The player whose hand signal was just done must repeat his own hand signal then do the hand signal of another player.
This continues until someone doesn’t realize it’s their turn or makes a signal that doesn’t belong to anyone. This person who messed up must then take a drink or shot.. whatever was decided on at the beginning of the game. The drumming never stops until someone messes up. The video below explains the Thumper drinking game for our visual learners.
