half-hour power

A college drinking game in which the participant(s) must take 30 shots of beer in 30 minutes at the rate of one shot per minute, often used as a pregaming tactic before the real partying begins.

More daring players may attempt an hour power, which follows the same rules over the course of an hour.

"Yo, you going to the frat party tonight?"
"Hell yeah, we should pregame with a half-hour power before we go."

Half hour shower of power. 

When you have a 30 minute shower, most likely it's not needed and you coulda made due with a 10 minuter.

person 1 - what the hell were you doing in there?
person 2 - It was my half hour shower of power.
