Satin is derived from a Latin word that has something to do with anarchy/chaos/rebellion. So technically your right, it is just a rebellion thing =P.
Though I don't know what it really means. Satin got his name from that word.
Upon further inspection I believe you are talking about the Church of Satan, which is an atheist alignment parody of Christianity. I believe those people are jackasses who only further to alienate atheist people from society.
