Edit
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.
Usage Example (2ch style in English)
