The act of exchanging smileys on IM, often to infuriate the other person. Can also occur in a Smiley War( the act of dueling with someone over the number of smileys you can use at once)
Annoying woman: " :) :P ;) :'( "
Stable Male: " Damn it i hate those stupid things, woulda STOP smileying at me?!
Annoying woman: " ;P "
A facial expression where the corners of the mouth are turned upward. Not only is a smile the result of happiness, the action of smiling actually makes you happy(very slightly, though). So go ahead, smile. It makes you happy.
