24 hour rule 

The 24 hour rule states that any partially consumed liquor left over at the host's house for more than 24 hours after the end of a party becomes property of the host. The host is not required to notify the owner during this period.

"Hey man, I left some rum here last week, did you see it?"

"I drank it, 24 hour rule dude."

"Fair enough."

24 hour rule 

The 24 hour rule? This goes hand-in-hand with the three day rule. The 24 hour rule states that you’re supposed to call the girl you slept with within 24 hours of said deed or she knows deep in her heart that you don’t give a flying fuck!

Did he call you after your slumber party?
No... and the 24 hour rule has never failed me. I guess he's just not interested...

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
