someone who performs utterly ridiculous acts that they think will make them appear cool but in reality make them look like an 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.

actin a fool; people who call other people artars are mainly doing it so that person can say he/she is not the only artar
