Gang sings or show business?

I have been always wondering the meaning behind the hand signs Lil Wayne, Drake or Birdman are throwing in pictures and videos. There is a huge variety of gang signs in the US associated to each particular gang. I did a lil research and before explaining or giving any theories, I would like to give a quick summary of famous hand signs used in the hip hop community, apart from the middle finger, the Okay sign or the thumbs up which are pretty much known worldwide.

- The West Coast sign: Middle and ring finger crossed with the index and the pinky finger spread forming a "W"

- The "Pitchfork" hand sign: Ring finger and the thumb touching each other while the other fingers are facing down forming a "N" as In New York or an "E" if facing left referring to the east coast.

- The "Shocker" or "Hang Loose" hand sign : Also known as "two in the pink, one in the stink" or "two in the goo, one in the poo". Same as the pitchfork hand sign but with the index and middle fingers touching, The sign refers to the act of inserting the index and middle fingers into the pussy and the little finger up the ass.

- The "Corna", or "Devil Horns" hand sign: Extending the index and pinky finger while the thumb holds down the middle fingers. The gesture symbolizes rock and roll. It was originally created in the Mediterranean and used as protection against curses or bad luck.

- The ''Shaka" hand sign: Extending the thumb and the pinky finger while keeping the three middle ones curled. It's a gesture of friendship having several meanings such as "all right", "cool", "take care"...(created by locals in Hawaii).

- "V" hand sign: Thumb holding the ring and the pinky finger down while keeping the index and the middle finger up and spread. The face of the hand must face the receiver. The gesture symbolizes victory or peace.

- "ILY" hand sign: Same as Devil Horns hand sign but with the thumb spread, the face of the hand must face the receiver. The gesture is to say "I Love You" (created by a deaf school). This sign is generally used by pop rock artist such as Pink.

Birdman’s picture here looks a lot like the pitchfork but instead of the ring finger, the middle finger is down, some people say that the sign is gang affiliated but I personally think it’s an exclusive hand sign for the label "Young money" in order to advertise it and make it look fashionable exactly like the famous Jay-Z's diamond hand sign representing his label "Roc-A-Fella"

But what I think can be interpreted as a gang sign and precisely "bloods" is Drake’s hand sign. The three partners like to show this sign which looks like an Okay sign but with the three upper fingers touching forming a "B".

The Okay sign itself is interpreted by some people as an Illuminati symbol representing the "occult 666" specially when an eye is shown trough the Okay circle like in the picture, many artist are suspected of being part of this sect including Lady Gaga and Beyonce. Jay-Z's Diamond sign also has this interpretation...

The theory of Drake’s affiliation to the bloods is heavily supported by Lil Wayne wearing red bandannas... In one of his songs, Lil Wayne even said "I keep a red flag….. fucking with them bloods now". I am not sure Lil Wayne, Drake or Birdman are associated in any gang activity at least not anymore; I think it has more to do with street credibility…
