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."

5 Second Rule

The rule that applies to lost or fallen objects, typically food, that hits the floor. The rule applies to general areas, and does not apply to anything in a bathroom. Using this rule makes it OK to pick up said object in under 5 seconds, under the presumption that no germs attached themselves in such a short period of time.

If your gum just dropped on the floor, pick it up and say "5 Second Rule", then place it back in your mouth.

5 second rule

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!"
(Proceeds to pick up dirty-ass rocket pop and suck the lint off of it)

5 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.

5 second rule

Rule invoked whenever dropped food is picked up and consumed in the presence of others. Time can vary widely depending on the type of food dropped: a sirloin steak at a barbecue may have nine lives, while a street vendor hotdog is declared unfit for consumption even before it touches the ground.

Once I saw it slip from his tongs, I asked the street meat vendor if I could get a new sausage.
