Merriam-Webster adds 'f-bomb' and 'sexting' to dictionaryAdd to Favorites | Glee
"Some of the new words this year provide colorful images," says Peter Sokolowski, Merriam-Webster editor at large. "Terms like 'man cave,' 'underwater' (when used to describe mortgages), 'earworm,' and 'bucket list' paint vivid pictures in your mind. They show that English-speakers can be very creative as they describe the world around them."
Some other newbies for 2012 include "copernicium" (a new chemical element), "mash-up" (thank you, "Glee"), "energy drink" and "cloud computing."
Sounds like a real "game changer" -- another new-for-2012 term defined by M-W as "a newly introduced element or factor that changes an existing situation or activity in a significant way."
