Sarcasm Is Not A Lowest Form Of Wit !
I value a proper sarcastic comment used skilfully more then anything else. And to prove that here is the list of uses for sarcastic comments:
1.) It can be used to hurt people's feelings if you wish so, or if they are complete dumbshits and you just want to point that out :)
2.) It can be used to relieve the tension in a conflict situaution, or you could get your head kicked in if you don't do it properly :)
3.) Sarcastic comments directed at yourself are a great icebreaker, or the person you are chatting up will think that you are a complete douche and just walk away with a bad taste in their mouth :)
I'm sure there are more uses for sarcastic comments but at this point in time I just can't be bothered to think of anymore and besides if I listed all of them myself that wouldn't leave any chance for you lot to come up with some "brilliant" ideas, now would it ?
