Like the 5 second rule and 10 second rule, except this one happens on a much dirtier floor, in which you are alloted no time to pick the food up and eat it.
Dude, don't eat that, look at this floor, that's a No Second Rule my friend.

An unwritten law dictating that if a food or other consumable item is dropped onto the floor, it may be picked up up and eaten within five seconds. The reasoning behind this is that dirt and germs take six seconds to transfer from one surface to another.
"Oops, dropped my popsicle. Five second rule!"

1. The term designated to the average time it takes a doctor to interrupt a patient who is describing their own symptoms. Coined in 1984 by Beckman and Frankel in the Annals of Internal Medicine. This is used by doctors to control the flow of pertinent information regarding the symptoms, keep focus on what's important, and keep the conversation brief.

2. An informal term designated to how much time it takes in average for a person or animal to completely empty their full bladder unimpeded and without forcing it. Briefly mentioned by the show Mythbusters during the testing of the myth "Peeing on Third Rail".
1. The patient may ramble on about their daily lives, but you gotta know when and how to intercede. In average, doctors learn when to speak in the examination at about 18 seconds. This is known a the 18 Second Rule.

2. Did you know that it takes you the same time to pee as an elephant does regardless of the fact that it's bigger than you? 18 Second Rule, man!

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.

The 5T second rule (five-tee second rule, 5-T second rule) is a rule that is secretly the 50 second rule (fifty second rule). The 5T second rule states that if you pick up food or drink within 50 seconds or less, you get to eat the food and drink the drink. It's actually not a real rule and just an excuse to eat food off the floor and drink food off the floor. In 5 milliseconds, there's already hundreds of germs and viruses sticking to the food and many more preparing to stick.
Frank: *chicken wings and French fries with ketchup and a Pepsi falls to the floor.

Frank: Uh, 5T second rule?

Dave: Oh! I guess 5T seconds is a pretty short time to wait to pick up the food from the floor.

*43 seconds pass.

Frank: *picks up the chicken wings and ketchup and eats it.

*Drinks Pepsi with a straw.

*Burps
Dave: Wait a minute! I thought you said 5 second rule. It's been 49 seconds.

Frank's daughter: That's filthy! Even 1 second it has germs.

Frank: Uh? It's got Vitamin F!

The First Rule of human food consumtion. If you drop the twinkie on the floor of your apartment and pick it up with 3 seconds, it's still good. If you try to put it in your mouth at any point past 3:01 seconds, you're a dirty bastard, and will probably die from gangrene of the mouth.

NOTE: This rule is not applicable in a gas station restroom (that's just wrong).
Don't touch it man! That bad boy is WAY past the 3 second rule!

The rule by which one determines whether or not food is safe after falling onto the floor. That is, if you are able to retrieve said item within 5 seconds, it is not dirty and is safe to eat.

* Note: in fraternity houses, this rule is the 1.5 second rule. Rule is invalid in the restroom.
Person 1: Oh no, my chicken wing fell on the floor!
Person 2: 5 ... 4 ... 3 ... 2 ...
Person 1: Got it!
Person 2: 5-second rule. It's yours, dude.
