Rule 19

Used in lifting weights originated from reddit.com:

You cannot criticize anyone's form unless you lift 90%+ of theirs.

The 90%+ extends to Wilks score to help normalize.

Good job - you can barely deadlift 200 and you are talking shit about someone who pulls 600. Rule 19.

The 1/19 Rule 

An excuse used when someone makes a leap in logic with no evidence behind it that leads to the solution of a puzzle regardless.

"Wow Ty, how did you know it was Mr. Red in the dining room with the knife?"
"It was quite simple, I just applied The 1/19 Rule and knew instantly."

19 minute rule 

A commonly held practice amongst urban males, by which at least one (though more commonly multiple) sexually active partners reside within a 19 minute commute of the male's place of residence, so as to allow sexual activity that takes advantage of early morning erections (that statistically last approximately an average of 20 minutes without stimulation)

Person A: "Not to be too much of a triflin' hoe, but does your girl meet the 19 minute rule?"

Person B: "Why yes, I am always inclined to follow such practical, time-tested, and, if I may be so bold, satisfying rules-of-thumb."

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!
