A good insult can be an absolute treasure. Sure, it might not be the nicest thing, but if it's creative, the perfect roast can be absolutely legendary and mind-blowing. Or simply hilarious, because some of the things people come up with are so specific yet spot-on that we can't help but laugh. Most of us will never be able to take down someone else's self-esteem like these people could, and that's why they've become known as "rare insults." If you want to brush up on the art of brutal takedowns, we're happy to introduce you to the following people who should probably be teaching a master class in insulting others.
