Yeah I have kicked a mirror, car, truck, but the best the "sack grab" You do this standing on you pegs twisting you body towards the a$$'d car and grabbing you sack. My fav!!!
I did a wheelie and the ass @ the stoplight afterwards had grampa baby about it. He told me he want to kick my a$$ and so I got off my bike and and said bring it. No reaction he just closed his window and drove off.
Another time this b!tch in BMW got pissed because I beat her to the light and got in front. She started sreaming out the window. I yelled back @ her" Dont make me slap a b!tich". She shut up.
