Have not had this on a bike, but in a car, a half full pint pot launched from a Fiat Punto hit my widscreen in the Manchester Airport tunnels, car was in the outside lane, three lads in it, I was in a Volvo 850 T5 so I went past and forced it to stop, I get out, there were three young neds in it and I was at the height of my weight training days so large and quite big, with a load of red mist on my side, I stomp over, three of them in it, they wouldnt open the window and reversed to get from behind my car, I laid into the side with my foot and left two nice dents as it screamed off.
Another one, stopped for a paper on a Sunday, got some peanuts as was starving, car full of Neds stops as if to ask directions on the way out and said "Excuse me mate, are you..................a F*ckign Gimp" and made ready for the off whilst getiting ready (I think) to gob on me, I pre-empted his potential strike by giveing him a half chewed face full of peanuts, his face was a picure, screwed off calling me names.
I will get a pasting one day, bit I cant back down as I cant forgive myself afterwards, when I ever have done, I make sure I get even somehow, I will use any means to get it off my mind.
Other than that, I am quite nice and placid if left to bumble through life without anyone p1ssing me off.
