rule 

A statement which denies people what they might want to do. Normally written after the event has happened. Does not stop people ignoring it, called breaking the rule, as most people are unaware of it, or think the rule is wrong. Breaking the rule usually incurs some penalty if caught doing so.

5 Second Rule 

A myth that says that if you drop food on the floor, and pick it up within 5 seconds then it's okay to eat. But research done at University of Illinois has disproved this, and says that food picked up in under 5 seconds had a significant amount of bacteria on it.

"Ewwwww! Your gonna eat that? It's been on the floor!!" "Yeah, 5 second rule."
