But, as luck would have it, I was just about to finish a book about Noah Webster who wrote the first American dictionary (I'll review it soon). The next day as I reached the final page, where it's talking about the changes Webster's dictionary has seen since it was first published in 1828, it says:
"... true to the spirit of Noah Webster, the company continues to track every new word in the language so that it can release an updated version of its flagship dictionary every year. Recent changes include the additions of 'chick flick,' 'blogosphere' and 'LOL' as well as the elimination of 'hodad' (a nonsurfer, who pretends to be a surfer), a term that the Gidget movies of the early 1960s popularized." (page 334)
That's so random!
