SPRINGFIELD, Mass. (AP) -- Here's something for your Twitter feed: "Tweet" has earned a spot in the Merriam-Webster Collegiate Dictionary.
The term, used both as a noun and a verb, is among more than 100 other new words in the venerable dictionary publisher's newest edition.
Some other newcomers include "helicopter parents" and "boomerang child," and the folk- and country-influenced music genre known as "Americana."
Merriam-Webster's president says he considers "fist bump" among the stars of the new words.
Though the knuckle-tapping action has been around for years, fist bump's place in popular culture was cemented by President Barack Obama and First Lady Michelle Obama when they did it at the 2008 Democratic nominating convention.
