Quidditch Rules

Refers to any competition or game, official or otherwise, where there is one task that has a significantly disproportionate effect on the scoring; Especially where this single task has a huge luck element to it.

This term originates from the rules of Quidditch, a sport in author J.K. Rowling's fictional world of witchcraft & wizardry, in which there are multiple ways to score a handful of points, but the if a seeker catches the Golden Snitch –an action that immediately ends the game– they receive 15x a normal scoring point in the game, thus almost always securing the victory even if they were significantly behind in the rest of the game.

We worked our butts off to score well all semester, but the professor pulled some Quidditch Rules bullsh*t and gave the team who did best on last week's assignment 15x the points of all the other assignments, so the team in last place won.

Dude 1: shit I forgot, I’ll tell her

85% Rule

Applies to sports bars that are always right near capacity, but you could always find a seat.

These unicorn bars are the best of both worlds for fans: A great atmosphere AND people know they could still get in without reservations.

Melissa: Where we watching the game tonight, Fam?

Jeff: Ugh, I totally forgot to make a reso, I have been busy all week.

Melissa: Ok, tip-off is in one hour, let's go to 99 Wings, they are an 85% Rule place.

Jeff: So good, and they have the best cajun rub wings.

Rule of Roelofs

When an action does not take effect during a potential period of time, it is rolled off to the next more optimal window of opportunity. This is not a function of statistical probability, it is simply the way things are and cannot be explained by logic or mathematical analysis; it just happens that way.

That smarty pants tried to explain with a rationale of probability that day shift didn’t receive a call, and that this had zero impact on night shift getting call. You would think he had heard of the Rule of Roelofs. Apparently not.

Granville Rule

Speak now or forever hold your peace. If you don't speak up, you don't get fed. Everything moves on pass you if you stay quiet. Used to make decisions faster and more efficiently.

Nancy always tells us which restaurants she wants to go to after the reservation's already booked and then complain about the food. Granville Rule next time we hang out so it's on her.
