One who cries a lot and worries constantly about his hair. Seen as the scum of the emo world and often acts as something other emo's can look down on and laugh. To be a 'Satansmaster' means you are a focus of mocking and ridicule, and rightfully deserve it.
"Oh, look at that scummy little Satansmaster. Lets laugh at his appauling emo hair and make our emo-selves feel slightly better."
