Researchers at the University of Vermont sifted through more than 10 million geotagged tweets from 2011 to map out the moods of Americans in urban areas.The list includes 10,000 words that have been rated on a scale 1 to 10 according to how "happy" they are. On the lower end of the scale are negative words such as mad, hate, no, boo, smoke and jail, as well as a colorful and thorough assortment of expletives.

Happy words include the omnipresent LOL and haha, as well as good, nice, sleep and wine, and food or beach related words. According to the list, rainbow is one of the happiest words and earthquake is one of the saddest.

Among the happiest -.vacation destination Napa, California, was determined to be one of the happiest cities along with Longmont, Colorado; San Clemente, California; Santa Fe, New Mexico; and Santa Cruz, California.

The five most bummed-out cities according to average word choices were Beaumont, Texas; Albany, Georgia; Texas City, Texas; Shreveport, Louisiana; and Monroe, Louisiana. Again, researchers found liberal use of swear words to be a key factor in a city's overall happiness score. Yikes! I can't imagine anyone in our great state that could be that bummed out - I mean, Mardi Gras, Super Bowl, festivals, great food - what's not to love?
