a reeeaaaallllyy big dbag. someone who acts out as a completely ridiculous asshole.

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.

Well this is a derivation of an ever-popular favorite, ass clown. The only difference being the substitution of one profane word for another. Shit clowns are people who you would normally consider ass clowns, but they smell really badly. So the use of this word is usually saved for those ass clowns with poor hygiene, including but not restricted to bums, beggers, democrats, Rasheed Wallace and the like.
