A wholly untrue rule that states that if your food drops to the floor/ground and has contact for less than five seconds, you can simply pick it up and eat it without risk of sickness. This is untrue, of course. Bacteria covers your food upon contact, it doesn't take five seconds for them to attach.
Guy 1:Dude, are you gonna eat that?
Guy 2:Yeah..
Guy 1:But it fell on the floor...
Guy 2:But it wasn't there for five seconds..so according to the Five Second Rule..it's all good.
Guy 2:Yeah..
Guy 1:But it fell on the floor...
Guy 2:But it wasn't there for five seconds..so according to the Five Second Rule..it's all good.

If at any point when you are intoxicated and feel the overwhelming urge to text anyone else, text a bro and he (and in very few cases she) will play along with any absurd trains of thought you might have while at the same time preventing you from doing anything too stupid... Like drunk texting.
Jack: You partying tonight?
Brandon: No, I have class in the morning.
Jack: May I invoke the Drunk Text Rule?
Brandon: I'll allow it.
Brandon: No, I have class in the morning.

The “send nudes” rule applies to the internet trend of sending someone elaborate pictures or videos with the hidden message of asking them to send you intimate photos of themselves.
The rule here is, if the person receiving the request for nudes is forced into enough laughter to not be offended by the request then that person must succumb to the request and send the requests nudes.
