What's everyone's favourite smileys and what do you think it's supposed to mean? And what's everybody's hated smileys and what do you think they're saying?

My fav: It is the generic statement of "hey, look, I'm smiling!!!"

and Because I look Asian :)

My most hated one: This one always get on my nerves when someone uses it. It's like "oh, you're sooooo stupid/I'm getting tired of this..."
