five-second rule
Dropped food doctrine
The five-second rule is the folk belief that food dropped on the floor remains safe to eat if retrieved within five seconds.
The premise—that bacteria need time to transfer—has no scientific basis, but the rule persists as humorous justification for eating something you probably shouldn't: Five-second rule! It's still good.
