Busty Rule

When searching anything on Google Images (without safesearch) applying the word "busty" will drastically change the results of the search, usually with gratuitous amounts of pornography and unrelated to the previous search.

Bob: I bet the "Busty Rule" doesn't apply to something like ramen noodles.
Oh shit...

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!"

five second rule

A simple rule stating that food dropped on the ground is still perfectly edible if it is picked up in five seconds. Ingeniously created by guys for the sole purpose of reducing wasted food and allowing a person that second chance they needed to enjoy their food.

Jason: I dropped my steak on the ground!
Chris: That sucks.
Jason: Nah, five second rule, I saved it.
Chris: Nice.

One Guy Rule

When a girl has a history of getting with many men. She meets a guy, falls for him insanely quickly, and now insists she is a changed woman and no longer wants to sleep around.

Wow, she has seen the same guy twice, it must be that new 'One Guy Rule' she talked about.
Looks like they've both settled down together, that 'One Guy Rule' worked.

November Rule

1. The unwritten rule that freshmen should be taken care of, not taken advantage of, until November 1st.
2. A similar guideline discouraging the teaching to freshmen of certain esoteric forms of hacking.

"At last, it's the 1st! Nuts to the November Rule, it's time to climb on the frosh and sketch on the dome!"
