No it doesn't!
Yes it does. Everything that is labeled sarcastic is not sarcastic, some of it is sardonic and mislabeled.
It depends on the situation.If it is done in a close friends association then it is not bad.Also it can be selectively used in other relation also but be careful enough when using.
the best kind is. The purpose of sarcasm is to make the listener realize how ridiculous the subject is. It doesn't have to be insulting to the listener necessarily, but it's likely making fun of something. Honestly, I can't think of an example when it is not at least a little insulting.
not necessarily. if you're trying to emphasize a point, or state the obvious it's really up to the other person whether or not they want to feel insulted or not.
thank you :)
They say it is the lowest form of Wit.
I can see you too ;))
Pretty much all of the time .. it's the nature of sarcasm to be insulting.
