You need to be either an idiot or terribly distant not to get sarcasm by the conversation itself, i use it for special occasions, like the odd time someone without kmowledge of the interwebs asks me something outside of support or pms

I normally use it to respond to ignorance or blatantly stupid questions and responses. I also use it sometimes to make myself sound superior, and to make those near me feel inferior. I'll use it with my friends on occasion jokingly with my friends.
