Fucking scum mate , only trouble is if you try and get back at them there gonna prob be carrying knives mate it's not worth getting shived unless you can handle yourself, it's happens to me a good couple if times but I'm quite handy when it comes to shit like that. Hooded fucking scumbag ninjas round our way wish they would all fuck off and die.
Hope your ok anyway , just remember what cypress hill said “what goes around comes around kiiiid"
You tried your best and you failed miserably. The lesson is 'never try'.
