A rule used by douchebag guys who think that waiting three days after a date to call means that the girl will want them more, when really it just pisses them off
I thought he was blowing me off, but he totally three day ruled me. Classic.

The "three day rule" is an outdated piece of dating technology popularized by such films as "Swingers." It is a seemingly sensible yet often unrealistic tactic.

The "three day rule" is a rule to prevent a man from appearing desperate or needy after attaining a girl's phone number that he (just) met. Following this rule, you are to wait 3 days before calling in order to create suspense and appear non-needy.

The truth is, it is far better to call sooner but to make shorter calls. This way you slowly but surely integrate yourself into the girl's life, and by ENDING THE CALLS YOURSELF instead of waiting for conversation to dry out, you eliminate any signs of desperation. If you wait 3 days, you may have lost emotional momentum and it may be harder for her to recall the attraction she felt, depending on how well you did when you first met!

A far better tactic to create suspense, for example, would be to send a text message instead telling the girl you will call her at 4:21 on Tuesday (or some other EXACT time), but actually call her at 4:30 that day.

None of this is to say the "three day rule" is completely wrong; however, it should definitely not be followed dogmatically.
Hey man, have you called Clarisse?

No, I'm using the three day rule. I don't want to seem desperate.

How is calling a girl desperate? You don't have to ask her on a date on your first call, you know! Just tell her something cool happened, chat briefly, then say you've gotta go and will talk later.

Are you sure? The three day rule is supposed to work on everyone.

Positive. Then on your next call in the next few days, invite her along somewhere if you want.

A rule established by the norms of society about the contact information received by people on the dating scene.

Scenario: A man receives a phone number from a woman in public. If he calls on day one, he will seem desperate. If he calls on day two, he will appear as if his interest is too strong and still desperate. However, if he waits until day three, he appears genuinely interested, and not clingy or needy.
Person 1: I got a girl's number today; should I call her tonight?

Person 2: No, you should give it the three-day rule, man.

An awesome rule, created by Jezus, explained by Barney Stinson in the sitcom How I met your mother.

The rule states that you should always wait three days before calling a girl. The three day rule was invented by Jezus, because he waited three days to resurrect.

Considered the fact that Barney Stinson stands behind this rule, makes the rule Awesome and legen... wait for it... dairy!

House guests, like fish, need to be thrown out after three days.
I couldn't let Bob sleep on my couch forever, so I had to enforce the three day rule. -or- That fish was no good to cook so it must have broken the three day rule.

Another widely used "three day rule" has nothing to do with dating. This three day rule suggests to wait 3 days before responding to something another person does that infuriates you. The three day period gives you time to calm down and think so you are not just reacting from having a button pushed.
I wss ready to flame George but decided to follow the three day rule and let my emotions die down.

Applies to any food in the house. If someone claims it as theirs, but doesn't eat it within three days, it's fair game.
