Sarcasm
1) n. the use of irony to mock or convey contempt.
2) n. a language in which it can be said that Justin Bieber is a brilliant male pop artist.
3) n. the ability to insult idiots without their realizing it.
Edit: Since this definition has caused a significant amount of bickering and unsolicited protests, I would like to point out that this was clearly meant to be sarcastic, meaning that although I personally don't consider Justin Bieber to be "brilliant," there is no denying that he is a talented world-famous celebrity.
