[Zan]

Many of my frnds use "*sigh*" in thier tweets..i want to know wht do they mean

[Shikhar]

*sigh* means to take a deep breath for some reason. i guess its not related to only twitter and is used everywhere.
it shows regret or relief depending on usage

Bahahaha, how cute!

It means they're sighing. *cough cough* <- I just coughed.

It's like facepalming. Same meaning.

Someone did something or wrote something stupid, so the person is *sighing* at it.

this is sigh, even though it is a dog but we often do it as well when we are usually tired or surprise at someone
