I really hate this girl. She is super selfish and rude. She seems to irritate every nerve I have. What can I do to give her a taste of her own medicine?

Start with being nice to her. Be friendly and actively courteous whenever possible. When she shows her selfish and rude side, simply let it pass without retaliating. Show her that the better way to behave is the way you choose to behave, regardless of what she does. If she sees that your courteous and genuine attitude makes you content, she'll start to see the error of her ways and will hopefully adopt a more friendly and positive attitude towards others. That will give her a taste of her own medicine.
