Do not use that site unless you want to look like an even bigger idiot..
Wtf.. they use their own terminology.. that isn't "net lingo" you can't define words to your liking.. look at the examples they have on their site:
:-X Big Wet Kiss
umm.. hello? since when did that mean big wet kiss.. I thought it meant you're shutting up
0*-) Angel winking
what kind of freaky winking is that? ;-) THAT is a wink.. not *-) X_x
I don't even want to look at the rest of the stupid crap they have.. All that site teaches newbies is to go around using symbols they think are right when they really aren't.
