10 Second Rule is an expansion from the 5 Second Rule due usually for being too drunk! By the time the food has been dropped, your mind figuring out it has been dropped and finally realising you DO have to bend down retrieve the food it's still fine to just give it a rub off and continue to eat it. (If you are drunk, so are germs, therefore it's going to take them longer to get to the food.)
Drunk Dude 1: *Been drinking all night, drops fat juicy chip from the chippy on the sick ass ground, watches it fall, looks upset* "Damn! Oh well, 10 second rule" *Bends down, picks it up and eats it*

Drunk Dude 2: *Agrees with the 10 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.
