The following gestures do not mean what you think they mean:

The Fist is a gesture of rebellion, not rock.
The Hand is a gesture of protection, not paper.
The V sign is a gesture of victory which became a patronizing sarcastic gesture to superiors resulting in it becoming an offensive sign.
The Finger is derived from ancient Greece and symbolizes a phallus, a common symbol of the Illuminati.
The Thumbs Up is derived of the Roman gladiatorial games where, contrary to the believe that an upward-turned thumb meant life and a down-turned thumb meant death, the thumb was used in a miming gesture as if the hand held a sword. Therefore, the thumbs up in its entirety means "death."
The Roc (forming a rhombus with both hands) is a symbol used by the Freemasons.
The Triangle is a symbol used by the Illuminati.
The OK gesture (index on thumb with remaining fingers relaxed) is considered sign of the devil. The sign resembles a stack of three 6s with two rotated slightly to reveal the top portion of each.
The Rock-n'-Roll gesture is considered a sign of the devil resembling goat horns, the goat being the face of the demon Baphomet.

The following symbols are cultist tags:

The lizard is representative of the fact that we are surrounded by reptillians in disguise (like on V).
Vulcans remind of the god by the same name whose own symbol was a smith's hammer, the same symbol used by the Illuminati to express their ultimate authority.
The compass is a symbol of the Freemasons.
