Hafshya
A hafshya is a person who will do anything to get their way, even if it means stepping on someone else's toes.
My uncle is a hafshya. He took my spot in the car and said I was being rude.
My friend's mom is a hafshya. She took the last dessert and said I was being selfish.
My neighbor's kid is a hafshya. He took my bike and then said I was a thief.
