The 50-50-100 Rule

An even more hyperbolic variant of The 50-50-90 Rule. In a situation where a subject has a 50/50 percent chance of getting something right, they will get it wrong 100% of the time.

This "rule" was popularized within the Super Mario Maker troll level community by popular Twitch streamer CarlSagan42, and is just one example of a reoccurring joke designed to showcase how easy it is to fool the average player into doing something wrong.

Player: *decides to collect a powerup which the level kills them for in the next room* "It's LITERALLY The 50-50-100 Rule. This happens EVERY time!"

The 2 year rule

or less younger. May not always apply to those 18 and older

If I'm 16, the 2 year rule allows me to date some one of at least 14 years old

The Applebee's Rule

A rule usually made among a close group of high school or college friends stating that the first person in the group to lose their virginity gets a free dinner at Applebee's paid for by the other members. The rule can sometimes be extended to include all members with the last one usually getting a steak dinner marking a celebration of entering adulthood.

Yo, I just lost my V-Card, are we still going through with The Applebee's Rule?

Two River Rule

After crossing two or more rivers to get to your destination, sleeping or hooking up with other people is no longer considered "cheating" on your spouse and everybody is fair game.

If I fly to Germany for a business trip and leave my wife behind, I am ultimately crossing two rivers, therefore, sleeping with other women is not considered cheating, because I've crossed two rivers, putting the "Two River Rule" into effect

ten minute rule

An urban legend holds that, if a student arrives on time for class, and the teacher does not arrive within ten minutes of the official class start time, then the student is entitled to skip that class for that day without receiving an unexcused absence. Few, if any, schools actually have such a rule; yet the myth endures because of the student appeal of such a rule.

The rule is not necessarily alleged to be ten minutes. The "five minute rule" or the "fifteen minute rule" have also been used in this same sense.

What the fuck, it's 9:08 and Kotter's not here yet! Two more minutes and I'm invoking the ten minute rule.
