5-minute Rule

The common courtesy of waiting roughly 5 minutes for a friend to respond after commenting on or "liking" a status on Facebook. If the friend doesn't respond within this grace period, one can assume they're offline or simply disinterested in your post.

Mom: "Katrina, it's 3:30am! Get off the damn computer and get some sleep."

Katrina: "Give me a second, I'm waiting for Jessica to write on my wall. I "liked" her status 4 minutes ago. I gotta wait for the 5-minute Rule."

Mom: "You don't have any friends...so stop pretending! And switch the damn laundry before you go to bed."

5 Second Rule

A myth that says that if you drop food on the floor, and pick it up within 5 seconds then it's okay to eat. But research done at University of Illinois has disproved this, and says that food picked up in under 5 seconds had a significant amount of bacteria on it.

"Ewwwww! Your gonna eat that? It's been on the floor!!" "Yeah, 5 second rule."

inverse 5-second rule

When you pick up something interesting on the ground and you hold it for less than 5 seconds, it is ok to put it back on the ground.

jim: dude didn't you pick that off the ground?
tom: ya.
jim: then why are you putting it back on the ground? you should just put it in the trash.
tom: nah dude. inverse 5-second rule.

5 second rule

A highly scientific finding that says that germs need at least five seconds to jump on food that falls on the floor, enabling the person who dropped said food to pick it up and safely consume it, as long as they do so within five seconds of dropping it.

"Hey dude, that cookie's still OK to eat, the five second rule's in effect."

5 year rule

Like the 5 second rule for food landing on the floor, or the 5 minute rule for leaving class when a teacher is late the 5 year rule is time frame after the wedding to have a bachelor or bachelorette party if said party didn't occur or was so lame that it isn't even worth a mention.

Married guy: Aargh! My bachelor party 4 years ago was crap... wish I could have done it properly.

Good friend: Brrrooo! 5 year rule! We throw you a bitching party this weekend! It's going to be the shit!!!

Now happily married guy: Yeeeeaaahhh!
