Response to bullies
Bullies want to increase their sense of esteem at the sack of others.
The solution is to be smarter at their game. Agree with their stupid remarks and add or exagerate them so that it is clear that you can laugh at yourself and in doing so reduce the effect.. This makes them feel more stupid. Eg. "you're a stupid asshole" reply: "really, i'm glad you've enlightened me. Any other insights?".
