Something most poeple on Urbandictionary, and the world, obviously know nothing about.

Most teenagers who claim to be satanists do not know the concept of Satanism themselves.

LaVeyan Satanism is the type of satanism where you practice self-indulgence, and believe that you are your own god. Nothing fucked-up or rebellious about that.

Theistic Satanism is the type of satanism where you actually do believe in and worship a literal Satan.

There is no reason to call this religion ridiculous, just take a look at Scientology.
People who hear the word "Satanism" quickly assume it is pure evil.

A religion and worship of the human body and the material world, not always the worship of the devil himself (unless you're of the Luciferian path). Satanism is type casted by the media along with witchcraft and paganism, as something evil... to be hated and feared whereas satanism does not promote violence, animal sacrifice or racial hatred in any manner. Satan keeps the church in business.

A misunderstood term. There are many different faiths under satanism the most common is LeVayan Satanism, founded by Anton LeVay. It is attached to the Church of Satan and the Satanic bible. It is a more atheist (as they prefer to call themselves) point of view. Practicing rituals and spell writing and incantation relates it to Wicca or Pagan groups. Though the group practices magic, majic, magick, majik, or how ever you would like to spell it they do not believe in a celestial being or "God" except for themselves creating the philosophy "You are your own God" a point of view meaning you choose your own destiny not a false being claimed to have created all the existence from nothingness. Another View of satanism believes Satan was the true creator and during an inquisition the catholic church stole satanism and turned it into the opposing religion. These satanists usually practice the Ars Goetia, or the art of summoning of the 72 demons. They practice summonings, rituals, and spells found in LeVayan Satanism. Another for of satanism believes the bible and everything it says but choose to fallow Satan and his army of hell. These satanists are/where common on the black metal scene especially in the 90's. Satanism can be related to Christianity and Judaism because of its extensive branches each believing very many differences.
Satanism is by far the most misunderstood religions.

Satanism is very different from the worshipping of the Christian Satan, or demons. It's an atheistic philosophy of life, celebrating man's carnal instincts, and not to supress your indulgences. Anton Szandor LaVey was the first person to give this way of living a life, and he chose Satanism. If Satanism has nothing to do with the Devil or demons, why does it have the word Satan in it? Satan is a symbol for indulgence, for what other people perceive as "evil". We believe that man is God, so birthdays are the most important of the Satanic holidays. The other Satanic holidays are the Solstices, and Walpurgisnacht (Hallow's Eve). The symbol of Satanism is the pentagram, with the head of Baphomet in it. There are nine Satanic statements, and eleven Satanic Rules of the Earth. The Satanic Bible was released in 1966, written by LaVey. It contains the books of Satan, Lucifer, Belial, and others. As well, it contains the Thirteen Keys, translated by LaVey himself. So, in short, forget what people tell you about Satanism. It's not doing drugs, killing children, or sacrificing animals, it's a celebration of indulgence and man's body.
"dude, you worship the Devil!"
"no, I practice Satanism"
"same thing!"
"go read the Satanic Bible, you ignorant wretch of a human being"

A widely misunderstood religion started by Anton LeVay.
The church practices self indulgences and frowns upon altruistic behavior. The Church of Satan in no way acknowledges the existence of any devine being neither good nor evil. They worship no devil, though the phrase "hail satan" is commonly used. However in the church Satan represent the repressed desires of all humans and therefore saying "hail satan" is to hail one's self.
It is commonly believed that the church of satan is a horrible group of people that should be feared. The CoS should only be feared if one is actually a member of an archaic religion which preaches self restraint and stupid moral systems that are truly outdated. To roughly quote LeVay one of the philosophies is if someone smacks you on the cheek smash him on his and ten times more for he that turns the other cheek is like the cowardly dog that roles over when kicked. Therefore the person above who stated he beat up on satanists at school was more a satanist than the person who laid there and took it while "chanting" the name of an entity that a true satanist would not even believe to truly exist.

Many religions have broken off from satanism including but not limited The temple of Set.
While conversing in my theology class I realized that the satanist seemed to know more about christianity and satanism both than the self-professed christian who merely reaffirmed his ignorance everytime he opened his mouth.

A religion based on indulgance rather than chastity, services include men dressed in long black robes and women dressing seductivly or nude. Does not promote multiple sexual relationships but does not chasty them if it fullfills the desires of the individual.
Satanism has nothing to do with the Satan of the bible.

Satanism refers to a wide range of mostly left-handed faiths, including (but not limited to):
a) Reverse Christianity
b) Setianism
c) Sat/tanism
d) Luciferianism (or original satanism)
e) LaVeyan satanism
f) Symbolic (or modern) satanism.
As a short description of each:
The most readily-recognised of these is reverse christianity. This refers to those who espouse vice rather than virtue and act in all ways to perform 'evil'. However, it is also the minority.

After that, LaVeyan satanism is the next most easily recognised. LaVeyan satanism is an ethical egoist organisation (that is, it supports the idea that the individual should serve themselves). It also contains a sense of pantheism, in that it holds that all people are connected to power and can use it to perform magic. It is based on the satanic laws of the earth, and was founded by LaVey.

Luciferianism is the veneration of Lucifer as a positive role. It derives from Gnosticism (a christian sect which believed that God was pure wisdom, and we should seek this wisdom), some members of which decided that God could not possibly be wise and that it was Lucifer who should be venerated, as a positive, wisdom-bringing deity.

Sat/Tanism is more obscure. The name is a pun on "being and becoming", and is a combination of self-venerating practices and earth magic ultimately aimed at apotheosis (becoming a god).

Setianism is a mystery cult (a religion in which one is initiated into higher and higher levels, a little like freemasonry), based around the veneration of Set, from the Egyptian pantheon.

Finally, Symbolic satanism is a catch-all term for anti-theistic or self-venerating practices, often involving magic.
a) Alfie is a reverse christian. He does evil for evil's sake.
b) Beth is a Setianist. She's about to take another initiation in following Set.
c) Craig is a Sat/tanist. He thinks he's found the road to apotheosis; we'll see.
d) Diana is a Luciferian. She venerates Lucifer in the hope that he will save her soul and grant her wisdom.
e) Ethel is a LaVeyan satanist. She follows the Eleven Laws of Satanism, and will act in her self-interest whenever possible.
f) Frank is a symbolic satanist. He performs ritual magic and hopes to perfect himself, but doesn't claim a long pedigree for his faith.
