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.
"Dude, this hotdog is awesome....damn, I dropped it on the ground. No big deal, its still good takes a big bite, 5 second rule!! mumbles with mouth full"

Get the 5 second rulemug. 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

Get the IM 5 second rulemug. 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.
