Yeah you say that you were under the influence of some alcool...
Alcohol.... and caffeine... and dope!
...The legend says that this style of dancing was invented while 2 therion fans were trying a new ritual dance in order to invoke a goat.
And?... how are you supposed to invoke a goat anyway?... you take some alcohol, caffeine...etc... and then you invoke the goat. The only thing that went bad is that the High Priest recorded the whole stuff... drank the rest of the alcohol... and well, you know very well what happened with the damn goat.
