My laptop is named "The Dude" (BL, obv). So I'm logging in one day in the lab. Kid from asia (china maybe I don't know) comes over to have me proof a paragraph as I'm the only native.

Foreign Kid looks at my start-up screen
FK: Ah, I see people say this, "dude" what does it mean
Me: Ummm, everything
<FK, stares blankly>
FK: I looked it up and it means dandy or yo, but it still doesn't make sense to me
Me: I don't really know what dandy or yo means
FK: They're GRE words
<Me, stares blankly>
Me: Have you heard of UrbanDictionary.com?
