A highly scientific finding that says that germs need at least five seconds to jump on food that falls on the floor, enabling the person who dropped said food to pick it up and safely consume it, as long as they do so within five seconds of dropping it.

5 Seconds of Direction is 9 guys consisting of One Direction and 5 Seconds of Summer. They toured together for One Direction's Take Me Home and Where We Are tour. These 9 boys are the reason that millions of fangirls had could not function properly and have major fangirl moments. But now these fangirls are hoping these 9 boys collab and go on tour again.
These boys, 5 seconds of direction, saved our lives.

The 5 second rule is used to suggest that food that has fallen on the ground/floor is still fine to eat, as long as it has only been there 5 seconds or less.

Commonly the rule is simply extended to however many seconds is necessary to declare the food still edible (ex: 20-second rule).
"Aww crap, I dropped my hot dog on the ground." "It's alright: 5 second rule."

Contrary to the belief, it is actually 5 seconds from when you see the food that you may consume it without it being dirty or at all harmful to your body because, come on, it's only been five seconds.
"Sweet! A cheeto!"
"Dude, that's been there for 3 days."
"But I just saw it, like, 3 seconds ago. 5 second rule yo."
