Rule 80 

Rule 80 of the internet: Hypocrisy invalidates any point or opinion in the context of ANY conversation

I know a guy that constantly contradicts himself, claiming other things are bad when he does it himself. Dude can't resist to break Rule 80 every damn hour he breathes

20/80 rule 

The rule guys refer to when they think about cheating on their wives/girlfriends.

Their wife/girlfriend is the 80%: she cooks, cleans, gives him all her loving, and has decent sex. But it's never 100%.

The girl he wants to cheat on her with is the 20%: she's very pretty, has a great body, and is perfect at sex. However, she's a slob/druggie/junky/alchy.

(Seen in Tyler Perry's "Why Did I Get Married?")

Bill: "I don't know, man. My wife's just not cutting it in the sex department, ya know?"
Joe: "20/80 rule, dude... think about it..."

20-80 Rule 

In any nightclub in America you go to, 20 percent of the guys there are getting 80 percent of the action. The other 80 percent of the guys are usually too chicken shit to do anything but watch the hot girls dance while sipping on their drinks and getting horny.

Always remember the 20-80 rule when you go out.

One cannot wear tank tops unless is is greater than 80 degrees out or they can combine curl more than 80 pounds.

Rick was breaking the 80-80 Rule so I made him put a sweatshirt over his frail arms

80/20 rule 

The belief that in a relationship, you'll never get 100% of what you want, so at most you get 80%. But some other person may come along and have that missing 20% you don't have. Some folks fall for the 20% just to realize they should've stayed for their original 80%. C/O Tyler Perry's "Why Did I Get Married?"

"Damn, my co-worker is so HOT and incredibly funny!"
"Think about the 80/20 rule, Becky. Think about it."

"Dawg! She is baaaad...34/22/36. Damn i would so hit that..."
"Whoa man; 80/20 rule dawg. Lisa is a good wife..."
