Are we talking theistic Satanism, LaVey's girl scout troop and other wannabes, or black magick in general? And what's your goal in asking this?
Seems to me you dont know much of what you are talking about.
Black Magic and ceremonial magic practice in general are all forms of Theistic Satanism. And your so called girlscout troops (which given they really were girlscouts of the cookie selling type they are still more awesome than you) has nothing really to do with demons and metaphysic entities, but with glorifying the real beauty of the true human nature and vices which the Catholic Church and the social contract (as in "living in society" aka the law) have put so much stress and effort into denying and punishing. LaVey's doctrine is basically the worship of oneself; something among the lines of "there's no God, there's no devil, we ourselves make our heaven or our hell and all should be free to make of this life a heaven or hell for themselves as each might fancy, as long as it doesn't fuck up with someone else's because they have the same right as you.
As for the topic here, it really much depends on what the OP means. In its true contextual origin, a Satanic ritual is any form of worship not directed the meccan (Judeo-Catholic/Islamic) God. Thereby any type of party, feast or celebration not directed towards Allah, Adonai,YWVH (Jahveh), God or Jesus of Nazareth is a Satanic ritual. Which basically means the 4th of July, for instance, would've been considered pagan and satanic back in the day, and so would Christmas (pagan celebration dedicated to de Solar Diety practiced by romans and persians on the night prior to the winter solstice around the time of their conversion to Christianity).
