"Dude, that's been there for 3 days."
"But I just saw it, like, 3 seconds ago. 5 second rule yo."
A popular axiom that deems food dropped onto the groud edible for a period of 5 seconds immediately following its release. Does not apply to porous or otherwise absorptive foods such as frosted cake or ice cream.
-Nah, it's O.K. Five second rule!
guy two: aww crap, butter move fast to make the five second rule. This stuff sure isnt good enough for a ten-er or a 15-er.
