A period of time devoted to the art of taking a shit. One may be limited to one hour tops, but while taking his/her "power hour", it can be as short as five minutes depending on that day's fiber intake.

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: that’s a minimum of 12 shots, I can’t do that. I’ll do a regular power hour.

Named after Interstate 270, a highway that forms a 55 mile loop around the city of Columbus, Ohio, a 270 Power Hour consists of a group of friends driving around the entire interstate and taking a shot of alcohol each time an exit is passed. Be careful, there's 28 exits. Drive at 55 mph to achieve victory in exactly one hour.
I took Lisa out for a 270 Power Hour date; let's just say it worked in my favor.
