"Jiong (Chinese: 囧; variant: 冏; Hanyu Pinyin: jiong3; British Cantonese: Gwing) is a Chinese character meaning a "patterned window" or "as bright as the light peering from outside the window". The character is now rarely used in this sense.
Internet emoticon usage
The character for "Jiong" is nowadays more widely used on the Internet as an ideographic emoticon representing a range of moods, as it resembles a person's face. It is commonly used to express ideas or feelings such as annoyance, shock, embarrassment, awkwardness, scorn or the internet meme "DO NOT WANT".
The use of Jiong as an emoticon can be traced to 2005 or earlier; it was referenced on 20 January 2005 in a Chinese-language article on orz. The character is sometimes used in conjunction with orz, OTZ or its other variants to form "囧rz", representing a person on their hands and knees (Jiong forming the face, while r and z represent arms and legs respectively) and symbolising despair or failure."
