The rule that states if any edible object should touch the ground it may still be eaten if picked up within 5 seconds. (No matter how nasty the ground or surface may be.)
Tanisha dropped an M&M on the wet and dirty bathroom floor but ate it anyway claiming it was safe due to the 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.

The rule stating a DOUBLE TEXT is ok AS LONG AS the second text message is sent within 5 seconds of the first.

When you pick up something interesting on the ground and you hold it for less than 5 seconds, it is ok to put it back on the ground.
jim: dude didn't you pick that off the ground?
tom: ya.
jim: then why are you putting it back on the ground? you should just put it in the trash.
tom: nah dude. inverse 5-second rule.

You know when you have some fried chicken on your plate and it's the last piece at the cookout and of COURSE you drop it on the floor. Then what do you do? After all, it's disgusting to eat food that fell on the floor. Well, the 5 SECOND RULE says that after 5 seconds, any food that fell on the floor immediately becomes un-germified. So after 5 seconds, eat whatever you dropped on the floor, cuz the rule is what really matters.
John: "Damn I dropped my slice of pizza on the floor."
Mike: "That's too bad."
John: "Oh well," ::picks slice up and waits five seconds:: "5 second rule!" ::BITE!::
