to be sent to your friends before the shit absolutely hits the fan.

When someone has way more information on your illegal doings than you do.

Named after Admiral Isoroku Yamamoto. Isoroku was adopted and the characters for his name read a certain way read 56.

He was killed in action because the Allies had broken the code the Japanese Navy had been using shortly after WWII began.

Roosevelt put a freaking hit out on the dude. Naval intellegence read a copy of his schedule and determined that he would be flying alone to Rabaul. Long range fighters where dispatched and Yamamoto ended up hitting a tree while traveling 300mph. This proved fatal.

The Japanese continued to use their compromised codes for the rest of the war.
Dude in the house texting his friend who is out side the house: You gotta get in here man, free coke, blow, booze, and the donkey show starts in 20 minutes.

Best friend out side the house and sees the SWAT team setting up a perimeter: 56! run!

Spending a ludicrous amount of money to perform a hand job in the front of a prostitute.....
Ill pay you over a $100 dollars if you watch me jack off.

This would be considered a request to perform a 56......
