What does 囧 mean? How do you use it?

i've found some materials about this character, and it turns out that this character's original meaning is "bright", but now people have assigned a new meaning to it, which is " embarrassing". like in this situation which happened on my team the other day: Sheed went for a defensive board and he didn't get it, instead, he tipped the ball in for the opposing team. you can say this play is very "囧".

it means embarrassing.when someone tells you a very funny even a little silly story,you could use 冏to express that kind of weird feeling.

i guess it means cry.someone is so sad,and she/he cry like a baby.

upset

in a shor word ,jiong means embarrassing and awkward,and the character 囧 looks like a face with embarrassing ,that's it ,the "jiong" have become a mordern-culture arising form the internet in China.
Mostly young guys like use it in chatting in the internet.
