Here's the most popular word in the past month from a rival word of the day. It is meh, and is a term indicating indifference, to be used when one simply doesn't care. For example:
A: What do you want for dinner?
The word is now sweeping the Internet, according to the Guardian. Used in the Simpsons. Defined by Danny Katz as "totally blank-brained can't-be-stuffed indifference." Scored a startling 5934 positive votes and only 514 negative in the Urban Dictionary, a prolific (too prolific) source of new words of all kinds. It is "a slang dictionary. With your definitions." Thanks Debbie for the source.
