:S

':S' Is used to express confusion. Often,it is directed towards someone else's stupid remark. For instance,if somebody is getting angry for an unneccessary reason. For general confusion,':s' is more likely to be used. Or,':S' Is used when someone cannot explain their anger. OR,it can be used by well-mannered people,at the end of an angry statement,to show that,although they are very angry indeed,they still have enough self control to make a smiley. OR it can be used to lighten the mood at the end of an angry statement. So that the person who the anger is directed towards realises that the statement is not an invitation to argue. i.e. 'I'm sorry, but you're post made me genuinely angry :S' The person,by adding the ':S' is basically saying,'You've made me angry,but my anger is justifiable. I've made my point,so let's end it there. Don't bother arguing with me.'
