7Day Theory

a great achievement in the game Counter-Strike/also means the 7 Day Theory based on Tupac Shakur-took Tupac 7 days to die, and myth was that he would be back in 7 years(still to be confirmed)

I pulled a 7Day Theory(PWNAGE/l337 move)

7Day Theory by Kyle Varney October 25, 2003

the 7 day theory 

also known as the don killuminati. An album by 2pac shakur. So called because the title song was thought of, written, composed and released in 7 days. The number 7 is related to the belief tha 2pac is alive.
e.g. his age when he "died" 25 (2+5=7) and the fact that he survived for 7 days before he "died".

person1: have you heard the seven day theory?

person2: Not only have i heard it but i believe it!!

The 7 Day Theory 

The theory of 2pac faking his death. The number 7 is involved with this theory.

7 Day Challenge 

To abstain from ejaculation for a full week. A true test of manhood, especially among a group of friends. It is unclear if the 7DC is more difficult while being single (masturbation) or in a relationship (intercourse).

Jesse: "What's up dog? Did you know if you don't ejaculate for 7 days your Testosterone levels go up 40 something percent? I tried to do the 7 Day Challenge but I failed. You should try."

Kyle: " Challenge accepted "

7 day reply test

This is a test performed on somebody who is not replying to your text messages or has broken the 24 hour reply rule.

The test is to wait a MINIMUM OF 168 HOURS (this is very important) after the last time you sent them a text, and then send them a very universal conversation starter.

If they break the 24 hour reply rule again, then you have proven that they do not want to text you. That's because the chance of them coincidentally not having 15 seconds of time to reply to your text in 2 24 hour periods that are a week apart (assuming they have access and service to their phone) is less than 1 in a billion.

The only possible way this can be the case is if their phone is physically removed from their possession or destroyed. Although this is quite possible, if you keep in touch with the person through other means (facebook, myspace, or especially a face to face conversation) you can find out for sure.

Peter: Damn this girl ain't texting me back, wow

Steve: Has it been 24 hours since you last texted her?

Peter: Yea, why?

Steve: Do the 7 day reply test, wait a week and send her a conversation starter if she doesn't reply 24 hours after that then her phone must be lost/stolen/broken or she ain't tryna text you

The 7 Day Theory 

Tupac Shakur faked his own death, son!

Of course Tupac is alive! The 7 Day Theory is correct, son! I saw Tupac the other day ... he was working at a Country Fair with Elvis & President Kennedy!
