Satanism has been used over the years to describe a variety of different belief systems in a number of contexts which range from the literal worship of a malevolent spiritual being (Theistic Satanism) to an individualist celebration of selfishness and pleasure (LaVeyan Satanism).  

The perception of Satanism by Christians and Pagans is "that which is opposed to Christianity" and Christian beliefs.  For this reason, a large number of cultural ideas and beliefs have been called Satanic for running counter to Christian beliefs. Popular culture is often dubbed Satanic as a temptation away from Christianity, especially if it deals with violence, sexual promiscuity, or other "immoral behaviours." This can apply to mainstream music, visual media, etc.  

Media that promotes Satanic themes often exist as an outlet for rebellion among teenagers and adults. Dark or "forbidden" themes may provide a sense of rebellion or individuality. Black metal follows this theme by using verses with Satanic elements. Tattoo and sticker artists may provide imagery that is supposed to be Satanic, such as flaming pentagrams or inverted crosses. 

Satanism fits into several conspiracy theories, often accusing government figures of worshipping Satan or being involved in Satanic practice. This often occurs when the government is being vilified for its actions by others. For example, many Islamic countries label the United States as "The Great Satan", and some may believe that the United States is actually controlled by Satan or is full of Satan worshippers. The Bush administration considered Iraq to be part of an “Evil axis”. 

Corporations can be seen as Satanic if they have any negatively viewed practices, are secretive, or have logos and symbols that coincide with perceptions of Satanism. The logo of Procter & Gamble was seen as Satanic for coinciding with a biblical passage.

Secret societies are often considered Satanic in nature, such as Freemasons and the Skull & Bones. Conspiracy theorists try to establish links to these societies and Satanism with iconography and numerology.
