In this game players pass around an invisible ball using three words: 'whizz', 'bounce', and 'boing'.
Whizz - the ball passes to the next player
Bounce - the ball skips over the next player and lands at the following player
Boing - the ball changes direction
The first player starts the game by specifying an initial direction of play (e.g. 'to my left') and saying one of the three words. Whichever player has the ball says one of the words to move it along.
If a player makes a mistake or hesitates for too long they must drink, and the game starts again.
