The 10 minute rule, and in some cases the 5 or even 15 minute rule, is an unwritten rule in schools, colleges and universities.

The rule is used when you have a class/lecture, and the idea is that if the teacher/lecturer is not there in the classroom within the said time period (5, 10 or 15 minutes - depending on what has been decided) then you can assume that they aren't coming and you can therefore leave to do other stuff/go home. This could also possibly be used in the workplace for meetings. (change 'teacher' to 'boss')

N.B. This rule can also be used/changed to deliberately skip classes. E.g. if you know that a teacher will be 10 minutes last, you can switch to using the 5 minute rule and leave before they get there, thereby skipping the class.
Student 1: It's been 8 minutes and Mr Greenwood isn't here yet.

Student 2: 10 minute rule?

Student 1: Good idea. If he's not here in the next 2 minutes, I'm off.

If a female does not enter within 10 seconds of a porno that is showing naked males it is a gay film but if a female enters the film within ten seconds it is not a gay film. AT ALL!

A variation on the "5 second rule" and "3 second rule", this term is mostly employed by street vagrants, or those who cannot stoop over to retrieve their food in less than 5 seconds.

phrase- simply means that if you're ever forced to go somewhere in public with your parents (the local mall for example), and you don't want to be seen in this humiliating situation, you walk 10 tiles ahead of your parents, nobody will ever notice that you're with them. The whole thing goes out the window if they scream your name out across the mall, but the entire situation can be avoided completely if you just bring your cell phone and they allow you to leave their watchful eyes.
John: I have to go to the mall with my parents, and for some reason they said I can't leave their sight.
Joe: No sweat man. All you have to do is use the 10 tile rule.

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*
