"Smiley," "I am sticking out my tongue," "I am sticking out my tongue, and I have a nose," "I am sticking out my tongue, and I have sunglasses" and "winking at you" are some good emo icons. The "smiley" emo icon was created by Scott Fahlman in 1982.
The emo icons are textual portrayals of a writer's mood or facial expressions. They are classified into three types: western or horizontal style, eastern or vertical style and 2channel style. In the western type emo icons generally the eyes are on the left, followed by the nose and then the mouth. The Eastern type emo icons are generally vertical. The 2channel emo icons were used by the Japanese people on 2channel and other message boards.
