Sonya: You should effigy her!
often times, people who qualify as effigies put on a false act that they are really nice or caring, but if you get to know them better or under different circumstances you find out that they're actually extremely rude or uninspiring; completely different than the original image they give. They're not true to who they really are when they're around other people, and will change how they act according to who they're with at any given time.
Girl B: Omgosh! i knooww! she is such an EFFIGY!!
Girl A: Legit!
