Cindy Brady Rule 

Also known as the Tom Brady Tuck Rule. Coined by Chris in Syracuse after the Patriots/Ravens game in which Tom Brady asked for and was granted a flag after an almost contact-free play.

Cindy Brady is a reference to the youngest child on the 70's TV show The Brady Bunch.

Bob: So why did you stop watching football?

Steve: Well, ever since the Cindy Brady Rule was adopted the game hasn't been the same. They protect the quarterbacks way too much.

3 month rule 

the three month rule is the amount of time a guy gets to ask a girl out. you have three months to figure out whether or not you see it going somewhere and if you fully want to be with her. it really should take three months but if it does and you still don’t know then leave her the hell alone. stop torturing that girl. if you don’t know by the third month if you see yourself with her then fucking leave. stopping wasting her time

girl: dyk what the 3 month rule is because it’s been 3 months already, and we still a aren’t dating. like do you want me or are you wasting my time? i’ve waited long enough so now i need to know, are we gonna date or not???
boy: idk yet, i still don’t know what i want
girl: cool *blocks him*

1/2X+7 Rule 

A algebraic equation useful for determining the youngest age-cutoff a female may be before the guy dates her. Let X equal the male's age ( Or female, if she's older.), while Y will represent the youngest age of a female a guy may date.

Next, identify the male's age and replace "X" with it. Suppose Jim was 15. We write it like this:

1/2(15)+7

Now, the Order of Operations principal applies here! Divide one by the two to get one half, and then find half of fifteen. Don't forget to keep the seven; It would be disgusting if Jim dated a 7.5 year old!

7.7+7

Add the number, matching up the place value carefully, and there you have it; Jim may date a 14.5 year old girl if he went for younger women.

If you are shit at math and/ or the 1/2X+7 Rule, here's a table for you, you lazy fucktards.

Male: Female:

15 14.5
16 15
17 15.5
18 16
19 16.5
20 17

Etc... So on, and so on. The coefficient is 1/2, while the constant is 7.

Nickelback Rule 

The Nickelback rule is to be invoked whenever a jukebox playing random songs inadvertently stumbles upon a Nickelback tune. The rule requires a listener to immediately insert money into the jukebox so as to hastily dispatch the aforementioned Nickelback "song."

Wayne: Hey man, you got a dollar?
Dan: Why?
Wayne: "Rockstar" just came on, Nickelback rule is in effect.
