The 19 minute rule 

The rule of never having a girlfriend who lives more than 19 minutes away from you, so that you'll always be able to get to her before your morning wood goes to waste.

Yo that girl was hot but it's a 40-minute drive to get to her, so I passed. Remember the 19 minute rule!

24 hour reply rule 

When you send somebody a text message and they do not reply within 24 hours there is a 95% chance that they readeleted your text and have willfully chosen not to reply

There is a less than 5% chance that they have lost their phone/phone was stolen, have been busy for a full 24 hours (so they couldn't even use their phone for 5 seconds, cause that's all it takes) or sent the message but the "delivery failed".

If it has been 24 hours and they have not replied, that's when you begin the 7 day reply test to confirm whether they want to text you or not.

Dan: Why have you been looking at your phone so much?

Steve: I'm waiting on Leann to reply

Dan: How long has it been since u sent her a text?

Steve: More than 24 hours.....

Dan: Don't you know the 24 hour reply rule? She more than likely readeleted your text man, do the 7 day reply test to see if she really wants to text you

Yale Rule 

The Yale Rule states that within five minutes of meeting someone who attended Yale, you will be informed of that fact. This is rather humorous, particularly given that Yale isn't that great a school.

"Greetings, my name is Throckmorton Q. Covington; pleased to meet you. I say, it's a fine day. It reminds me of when I was a young lad attending Yale...."

Ha! The Yale Rule's been proven once again!
