In America we call this practice assault and I do believe you would get shot with a gun if you tried it.
A 'Past-time' of gangs of complete idiots who go out and randomly hit/assault/rape people while recording it on their mobile phones, then distribute the video to otherpeople with camera phones.
These people are complete fuckwits that need eradicating from the face of the earth. No one should ever do anything like that to another human being. People like this should be shot so the likes of them will not plague the earth again.
My mate was 'Happy Slapped' when we were all in the park once. He was on his way home, and some random chav walked up to him and hit him while his mate taped it. My friend had to have stitches in his gum as the punch ripped the skin apart inside his mouth to the point that he could get his finger all the way up through his cheek...
chav 2: Yo totaley.
guy: (after being slapped) What the fuck you gonna die now, you son of a bitch (grabs knife and stabs chav in the brain through eye socket).
The chavs who engage in this don't seem to recognise it as assault or have any kind of conscience, which is very worrying. How long will it be before we read about "happy rapes" or "happy murders"?
