the person who stays sober at a party, club, etc. and keeps his/her friends from hookin up with grenades, landmines, or just someone ( or people) they shouldn`t

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.
