@Yiiko Yes poser can be used to describe an individual who is fake af, but I don't call Diana a poser because her power as a saint is dwindling or anything. I call her a poser because she acts and most definitely believes she is the most understanding or caring person in the world who can do no wrong like as if she's G**'s gift to humanity, but in actuality she is a self-entitled bi*** who is incapable of understanding that she can be wrong and hurts practically everyone she around her.
