When I was a teen I had a lot of problems with being teased and bullied. In the 10th grade one of my coworkers at a Library taught me how to deal with this problem and it hasn't been a major problem for me since.

When I was clumsy, I learned how to laugh at myself and make jokes about my clumsiness well before anyone else could. Then everyone could laugh, but people didn't feel like they needed to make the jokes go to the darkside as much.

If I said something accidentally crude or sexual, I would just play along with everyone else that the stupid thing I said was intentional to make others laugh.

If someone was making fun of some core aspect of myself, I turned the SAME joke around right away so that I made fun of a core aspect of the harrasser. This usually makes the harrasser realize that they went too far and why.

I still haven't figured out how to deal with Physical harrassment. The only thing I have found to help is to turn my voice to ice and say "How would you like it if I did that to you?" When people go "cold" instead of crying/upset, you scare others. That fear sometimes keeps them from bothering me again. Practice in the mirror your "cold" expression and tone of voice. If you don't think your bunny slippers are scared of you, keep practicing...
