According to the MDBG Online Dictionary: 囧 jiǒng - Variant of 冏, velvetleaf (Abutilon avicennae), plant of the jute family / bright / used as emoticon ("smiley") meaning sad :-(, depressed or frustrated I assume it occurred in the latter context, that is, meaning :-(

well actually it is a caracter widely used in BBS, forums. It looks like a brow-down square face, therefore it describes how a person feels after he comes across something strange, awkward vividly. You will not find it in the textbook or some articles. Whether is is compiled to the dictionary is still unknown to me. Trust me coz i m a native. Haha~~

囧 jiǒng this word means a countenance when u thought that u have much more trouble or have some setbacks. this is a new chinese word its appears in bbs.

囧 jiǒng originally means light ,bright. but in these two years ,囧 appears in chinsese bbs,forums frequently, no steadfast meaning ,its used just when you feel upset ,angry, disappointed,embarrassed,powerless to do something etc. yea, you can say its like a loony tone character or use.

Is it a typo?
