A drinking game involving a can of beer (lager) and a group of
people.
The game starts by the first person shaking the can as hard as possible in
time to the rest of group chanting "Dan-ger can, Dan-ger can, Dan-ger can!" After the 9th
shake the shaker smashes the body of the can into their head with as much force as they dare.
This continues around the group until a fracture appears in the can. If it is just a small leak then the person who caused the can to leak then they must cover the
hole, and repeat the process until the hole opens up. The smasher then attempts to drink the resulting deluge of beer as the rest of the group cheers/avoids the
rain of beer.
