A rule describing the amount of time that a magical force field surrounds a dropped piece of food, after which the force field drops and the food can become dirty and not edible
Shaniqua dropped her Oreos on the floor, but she still ate them because of the 5 second rule.
If food drops on the ground, you're still allowed to eat it if it's only been on the ground for 5 seconds or less.
Person 1: Oh shit I dropped my pizza slice
Person 2: 5 second rule!
Person 1: *eats pizza*
The window of opportunity for picking up food you dropped on the ground, dusting it off and eating it.
Person 1 - Drops sandwich
Person 2: "It's still good... 5 second rule!"
A long standing rule in which any food which is dropped on the floor/ground is still "good" and edible if it was only in contact with the surface for less than 5 seconds. Incorporated mainly by clumsy children but is often used by teenagers and adults as well.
The tacit requirement in ultra-clean American society that dropped food must not lay upon the ground for longer than five seconds in order to be still edible. Certain requirements about food type (i.e., non-sticky or attracting of dirt particles) generally apply.
Dude! I dropped my Dorito! Five second rule...still good.
A unspoken rule where if any sort of food falls to the ground, if you pick it back up in 5 seconds or less it is still okay to eat.
Oh no i dropped a skittle, its only been 3 seconds, its still good.
The '5 second rule' applies when food comes into contact with an object that is tainted. If it is removed from the tainted object in 5 seconds or less, then the food is considered safe for human consumption and eaten as if nothing happened. If it stays on the tainted object for more than 5 seconds then it is considered unfit for human consumption and is discarded.
I'll bet that fat kid eats the cookie he dropped on the floor even though the 5 second rule is up.
when it is okay to pick up a pick of food or candy from the floor if it has been on the floor for 5 seconds or less, as if germs and filth cannot adhere to an edible morsel during that time frame
Go ahead and eat the m&m -- the five second rule is in effect.
