A common knowledge webcam rule stating that it's okay for straight guys to jerk off with each other on cam as long as it doesn't exceed 5 sessions. If it exceeds 5 sessions, then they are gay. Derived from the "5 second rule".

Get the rule 5 mug.
When you drop a food on the ground, you have 5 seconds to pick it up before the germs come on it. After you do this, you blow or wipe off the food and eat it. This doesn't apply to sticky foods and dirty floors.

*Frantically picks it up*

Time you should wait before interjecting your opinion when walking up on two (or more) people in a conversation.
John and Fred were talking about Gun control, and Mike walked up and said that "Obama is going to take your guns away", but if he had waited 5 minutes he would have known they weren't talking about gun control at all, but how to shoot a gun. John says, "5 minute rule" and then everyone understand, he shouldn't have gotten into this conversation at this point. (And looked like an idiot).

Get the 5-second rule mug.
A variation of the 5 second rule, which dictates that food dropped into an awkward or uncomfortable place is still edible if retrieved within five minutes. Often conceived to be a more chivalrious instead of just plain ol' disgusting, especially if a man retrieves food dropped by a woman and eats it himself, replacing her loss with something that didn't touch the floor. It is also a more applicable rule than the 5-second variation when the moment of dropping the food is particularly ironic and demands a short pause for the appreciation of the twistedness of the world.
1.
Girl: "No! I dropped my Mars-bar behind the computer desk! T_T"
Boy: "Here, have mine, I'll invoke the 5 minute rule." Boy proceeds to fish the Mars-bar, and emerges victorious after a few minutes of shuffling under the desk.
2.
Dropper: "...so I was late to get up, my car was stolen, when I got to work my boss said not to come in if I can't get there in time, and-- here I go, dropping my sandwich on the floor. Perfect." Dropper stands still for a moment before picking up the sandwich.
