Well mine is kind of complex, well a bit
years ago when i first started on the internet i used to chat on irc or internet relay chat - fun uptil IM became the cool thing, anyway i started on many irc networks, but ended up on a network ran by mtv, at that point i went through the wow i need a cool moniker faze, i used demonlord for a bit, till i realized it was unexciding, on the mtv network i came up with a name.
i have a stuffed goat at home that a reletive gave me, i used thegoat for a short while, but ended up combining demon with goat - so i am the demongoat (evil baahhh) as an alt name i got by DG
as for the reverend part i really am one
its also sort of tongue-in-cheek to use it since i would be kicked out of any church based on my preaches
