Shit-mother-fucker said quickly with only the first syllable of each word. (Excluding where SHIT is one syllable. But you can't have the whole word in there, or it doesn't flow.)
Either pronounced shi-mah-fah, or shi-muh-fuh.

Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.
