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.

"Hell yeah, we should pregame with a half-hour power before we go."

noun: a clock-watching form of procrastination, in which the procrastinator schedules the "start time" of a dreaded task based on the next "half-hour" mark of the clock. For example, if the clock reads "1:35", a procrastinator employing the half-hour clock technique will start the task when the clock strikes "2:00", usually filling in this time gap with activities such as web surfing and masturbation. The technique is popular amongst perfectionists, numerologists, the obsessive compulsive and unemployed spectrum of procrastinators.
Hey, it's 4:47. Did you finish writing that cover letter?

Actually I did not. I was waiting till 5:00 to start. I'm using the half-hour clock technique.

The Ultimate Hangover cure.
The morning after partying a little too hard, you go into the shower intending on waking yourself up, but find yourself too tired and sit down.
Can go from fifteen minutes to upwards of an hour (depending on how big your hot water tank is)
Nicki was so bombed last night she said the only cure this morning was a half-hour sitdown shower.

That hangover was so bad it required not one, but two half-hour sit down showers!
