This is a smiley used in any situation where you have no clue what other smiley to use. It makes you feel like a complete idiot to run out of smileys. However, once you use it, BAM BABY! You're back on the route to awesomeness!

This is also known as the retarded smiley. It is used to express feelings of massive retardation.
