Also known as: タンヤオ(AA), ダディクール, タンヤオ(アスキーアート)
A 2channel meme, originally performed by ASCII Art character DaddyCool, who regularly makes errors in his Mahjong yaku score calculations. The joke is that the hand is not a tanyao worth only 1 han, but rather a Suuankou-tanki yakuman hand worth 13 han.
