The game consists of passing a 2 litre bottle of ice-cold Strongbow cider round a group of 4 - 8 people. The object of the game is to down as much as possible during your turn whilst the other players taunt you, insult you, poke you, tickle you, make jokes about your mother and generally try to make you spill cider all over your face. Works best if players are already drunk. (Also much more amusing this way.)
Common side effects of playing are violently painful brainfreeze, crying, projectile vomiting and becoming utterely wasted very, very quickly.
There is no real winner in the Strongbow Challenge.
