Willie: My mother said it's the law that I need to have my permit for another year before I can get my license...

Dan: Willie, did you notice all of us only had our permits for six months? We're two years younger than you and have our licenses already.

Willie: Durrr, I didn't really think about it... *proceeds to stare off into the distance with a blank look while making indistinguishable noises*

Dan: Frickin' dumbohead...

Someone who uses words such as gurl instead of girl, boi instead of boy, and other really retarded and lazy stuff like that.
