Revenge Hot is the new level of hotness you strive to achieve after being scorned by a romantic interest or bf/gf. This is shallow, superficial and petty and DOES make you feel better.
The goal here is twofold:
1) Ideally, he/she who scorned you will feel like an idiot the next time they see your even-hotter-than-before self.
2) By increasing your hotness you increase your chances of finding a better candidate next time around.
Jennifer Aniston gets exponentially hotter every time she gets shunned by a love interest. She is the master of revenge hot.
