Actually... They often DO get ganged up on...
What do you think when you are suddenly punched in the head by someone with 5 or more friends behind them...?
A different thing to if it was just one on one i'll bet...!
And what bothers me most is when its five GUYS watching another GUY punch a GIRL on a bus as has been seen before on these things..
F***ing disgusting... If I ever am there when something like that happens, I'll be beating the shit out of them with no hesitation...
