Catfight (also girl fight) is a term for the altercation among women, often characterized as involving scratching, slapping, hair-pulling, and shirt-shredding. It can also be used to describe women insulting each other verbally or engaged in an intense competition for men, power, or occupational success. – Wikipdedia
From the definition, these women probably should be hating on each other but on GMA’s high-rating afternoon drama D’ Originals, stars Kim Domingo and Arny Ross find it more satisfying and more fun when the catfights are intense because it is part of their job and their characters are written that way.
