There's a category of speech that I think is best characterized by the slang use of "Bite me!" It's said in an emphatic but not angry way, usually in response to a verbal touche' by another person in the conversation.
What is the term for this kind of speech type/category? Mizarchivist called it "flippant" and that's sort of in the right direction. It's not "sarcasm" nor really "snarking" - in fact it's something that may be a response to someone else snarking at us.
It's a retort, of sorts, but not really. "STFU" is sometimes used these days in online discourse in the same place, I think.
Anyone have any idea what this sort of thing is called?
EDIT: I think 'rejoinder' is probably the closest to the sense of what I was thinking.
