important Questiiiiiiiion

Cos they think it makes them Популярное and tough when they're being bitchy but it just verifys that they're a class A spanner :)

Cuz probably both girls are ugly and the other thinks the other one is beautiful hahaha :P

Maybe it's a defense mechanism. Having been called ugly most of their lives they know how much it hurts? So they use ut to strike back at someone else.

They do that to build self confidence for themselves while crushing other's self confidence.

Beacause they don't feel good about themselves
