three night rule

a sacred custom dictating that if someone is not a family member or an intimate friend, then one may only sleep in their house/apartment for three nights at most. Violating this is a high offense against one's honor. Go to a hotel.

Rather than spend a fourth night in Alex's San Francisco apartment, Bob took a train to San Jose and slept in a ditch. This way, he observed the three night rule and preserved his sacred honor.

one-titty rule 

a cinematic axiom defining classy, "artistic" nudity; Hollywood nudity is typified by exploitative close-ups and medium shots that both light and frame titties for the clearest view possible of the entire upper torso; art cinema, conversely, tends to abide by the one-titty rule, by which, through either framing, lighting, or, staging, or some combination of the three, only one nipple is visible at a time.

Sure David Cronenberg's "Crash" is possibly the most sexually explicit movie of the notorious pervert's career, but the Canadian master is careful throughout to observe the one-titty rule.

The Nintendo Rule 

The rule that requires one to blow into the ports of all electronic devices before connecting them. This rule derives from the popular and identical act performed while inserting an original Nintendo cartridge into its system, which would usually not read the cartridge if the rule was not properly followed.

A: The controller isn't working again
B: Did you follow the Nintendo Rule
A: No dude that rule's old and outdated
B: No it's not. Let me see it
*B applies Nintendo Rule*
*Controller works flawlessly*
B: See I told you The Nintendo Rule works

5 year rule 

Like the 5 second rule for food landing on the floor, or the 5 minute rule for leaving class when a teacher is late the 5 year rule is time frame after the wedding to have a bachelor or bachelorette party if said party didn't occur or was so lame that it isn't even worth a mention.

Married guy: Aargh! My bachelor party 4 years ago was crap... wish I could have done it properly.

Good friend: Brrrooo! 5 year rule! We throw you a bitching party this weekend! It's going to be the shit!!!

Now happily married guy: Yeeeeaaahhh!
