when some kids throw you a stone in your back and scream Sharmutaaaaaaaaaaaaa

It just happened to me the other day, out from my jeep under the heat at the centre, group of young kids scream sharmutaaaaaaa to me and i didnt even turn my head to them, they got pissed off and throw me a stone.

the third time, i took the stone and threw it back to them. In my country i might be beat them up already..huh! naughty boys....
