Take one shot of beer every minute for an hour. This can be more or less potent depending on what kind of beer you drink. From strongest to weakest, your choices are malt liquor, ice beer, regular beer, and light beer. To make a power hour even better, burn a 60 minute CD with 60 1 minute tracks. Play a different song for every shot you take!
Ilan: I doubt I could last the full hour.
Todd: It depends on what you drink... lightweights can roll with the light beer. If it's not enough get more drizzed later!

Unlike the regular power hour where you take 60 beer shots in one hour. This power hour was brought up with a bunch of hooligans that play rugby. This power hour consists of the nastiest hard liquor and you take one shot between 2.5 and 5 minutes depending on your tolerances. This is not for the faint of heart and will lead many to black out. Player be aware! This task can prove to be Difficult #hooliganrugby
Teammate number 1: wanna do a power hour?

Teammate number 2: thatโ€™s a minimum of 12 shots, I canโ€™t do that. Iโ€™ll do a regular power hour.

A drinking game that means taking a shot of beer every minute for one hour which, using math, means drinking 5 beers in an hour. Greatly aided by using the program iPowerHour to use music to time the event.

A drinking game (originating in Upstate NY/Capital District area).

Usually played, just prior, to heading out to the bars & clubs (A.K.A. "pre-game drinking" or "pre-gaming").

RULES: using an egg timer, or clock... every participant drinks a completely full shot glass of beer every minute, on the minute... for a complete hour.

This game is used as an easy way to get a quick "buzz"... yet difficult (for some) due to the constant smaller quantities of alcohol, timing, and aeration of the beer.
Person A: "Let's get toasted before we head out to the bars!.
Person B: "Alright!"
Person C: "I think it's time for a Power Hour!"
