Yikes, where to begin...
Er, I use "wicked" too much lately. Like wicked cool, wicked awesome, etc. it's a wicked bad habit. That, and rad. Lots of "rad." I think rad is a totally underused word. Unless I'm using it in speech. Then rad might be my new epic. I say it a lot.
Also, like. I like using like. Like is a fun word.
What gets really wicked crazy, is when I can jam them all together. It's, like, wicked rad to talk like that. Or not. But I do. [sub][sub]Leave me alone!!!![/sub][/sub]
That, or the phrase "I know, right?!" in a sort-of sarcastic-but-not-really context. It's an easy out for silly statements by others when you don't know what else to say...
