According to the book of Genesis, God placed a mark on the world's first murderer before sending him into exile. The mark of Cain indelibly branded its bearer as a criminal and social outcast.

Im hungover so Im chillin and researching Russian gang tattoos, as you do. The Russian prison population is one of the largest in the world. From the mid-1960's to the 1980's, 35 million people were incarcerated, and of those, 20-30 million were tattooed. Now Russian tattoos can be very detailed and meaningful and they are also used to show what gang your in. There are various different gangs in Russia such as the Aryan Brotherhood (white racist gang) Neta - Puerto Rican-American & Hispanic. Black Guerrilla Family - founded in 1966 at San Quentin State Prison originally by Black Panther members, and various others which you can of course see by now are segregated either through ethnicity or religous beliefs. Anyway, the tattoos are painfully applied with needles and electric shavers, using ink made from urine, soot, and shampoo but boy do they look good. Here's the meaning to some of them...

5 dots to indicate that the person has been in prison. Can also mean in other cultures the reminder of your attitude towards women and the police (Thomas Edison also had one on his arm)
Cats face - Indicates that one is a thief for life. Miaowf
Little finger - Anarchist
Third finger-that they were an orphan or the motto 'trust no one but yourself'
Middle finger: is in a gang
Forefinger-a ‘leninist’ bandit. (leader of a group of expropriators)
Spider or web - drug addiction
Barbed Wire- Life sentence with no parole

Monasteries, cathedrals, castles, and fortresses are often tattooed on the chest, back, or hand. The number of spires or towers can represent the years a prisoner has been incarcerated, or number of times they have been imprisoned. The phrase, "The Church is the House of God," often inscribed beneath a cathedral, has the metaphorical meaning, "Prison is the Home of the Thief."

And here's some Russian gangster rap. I cant tell what he was saying but I think he is sad.
