This tag referes to the ASCII-art "uso desu" (ウソです) which means "it's a lie,"and is used in [[2channel]], Japanese biggest BBS.
The AA is as following
     *      *
  ＊  ウソです  ＋
     n ∧＿∧ n
 ＋ (ﾖ（* ´∀｀）E)
      Y     Y    ＊ 
and used to completely deny all text written in the 1st comment of the boring thread (mainly in 2nd comment.) Additionally, it is a kind of manner in 2ch to write "A lie, I see" (なんだうそか) immediately if you see this AA.
