Believe it or not, that “word’ (w00t) has been picked as Merriam-Webster’s Word of the Year – even though it isn’t (yet) in the Merriam-Webster dictionary.
As for using w00t in a sentence (properly) – just insert it where you might normally say “yay.’ As in, “w00t! I won the Word of the Year contest!’
As for the rest of the list:
- Facebook – though not necessarily as a noun referencing the social networking website of the same name. Think verb – as in “Have you facebooked those photos from the party last weekend?’, or “Did you facebook today?’ or to look up someone’s profile on Facebook (“I facebooked Sarah the other day…’)
- Blamestorming – think brainstorming with a more “sinister’ purpose; sitting around in a group, discussing why a deadline was missed or a project failed, and who was responsible.
- Pecksniffian (an adjective meaning unctuously hypocritical. It’s etymology harkens back to Seth Pecksniff, a character in Martin Chuzzlewit (1843–44) by Charles Dickens.
- Sardoodledom (that one you can look up yourself)
