Centurion is a drinking game that involves downing 100 shots of beer in 100 minutes (i.e. one a minute). The game is considered difficult to complete without vomiting due to the large amount of liquid being consumed (100 shots is approximately 6 pints) in a small period of time. In some regions, anyone who munts is eliminated; in others, the reconsumption rule states that anyone who munts may continue in they munt into a pot glass and then drink it again before the next shot is due.

Anyone who reaches 100 is declared as a "Centurion". In competitive Centurion, the places can be decided either by continuing to take one shot each minute until only one remains, or by getting all Centurions to participate in a three pot scull-off, with the quickest being designated the winner.

There are similar games of 150 shots in 150 minutes (Elite Centurion), 60 shots in 60 minutes (Power Hour), 200 shots in 100 minutes, and 100 shots in 50 minutes (Monash Centurion).
