Making fun of yourself, laughing with him or ignoring it is the worst thing you can do. It´ll only make things worse.
I was in you position until I was about 17 and stopped being a pu$$y. The reason they make fun of you because you never set your boundaries. The first time they made fun of you, you should have told them in a serious calm manner to fvcking stop it.
Now all you can do is to gaze him straight into the eye and tell him if he makes fun of you one more time you´ll break his nose.
If he makes fun of you again then punch him in the nose.
