one of my favorite words to use, "meh", was found in the dictionary. I kind of liked it better out of the dictionary. I don't like using words that are so formal and words found in the dictionary are definitely formal.
meh: an expression of indifference or boredom, or an adjective meaning mediocre or boring.
at least they nailed the meaning.
example: "chet: want to hang out? me: meh."
