MADE MAN CEREMONY
When you're a member of the Richman Mafia Family in GTA 5 and have proven yourself worthy of being higher status within the family, you'll be made (known as a 'made-man'). To be made, a ceremony is conducted with the new man having to be "straightened out". This involves being knifed into the family.
Valachi gave the most well-known description of the ceremony:
“I sit down at the table. There is wine. Someone put a gun and a knife in front of me. The gun was a .38 and the knife was what we call a dagger. Gladmadacus [the boss] motions us up and we say some words in Italian. Then KettleKorn304 pricks my finger with a pin and squeezes until the blood comes out. What then happens, Mr Gladmadacus says, ‘This blood means that we are now one Family. You live by the gun and the knife and you die by the gun and the knife.’”
