"Garbage time" and "Tommy John surgery" are among the sports-related terms that were added to Merriam-Webster's dictionary Monday.

The dictionary announced it was updating its database to include 640 new words and phrases — or new uses of existing words and phrases. The dictionary makes regular additions to reflect changes in usage.

"Garbage time," of course, refers to the closing minutes of a blowout — or, as Merriam-Webster defined it, "the final moments or minutes of a game in which one side has an insurmountable lead, substitutes often enter the game in place of starting players, and scoring is typically easier because of looser defensive play."

"Tommy John surgery" is most often used in baseball, referring to the popular procedure used to repair a torn ulnar collateral ligament. John, a four-time all-star pitcher, was the first player to undergo the surgery in 1974 and went on to pitch an additional 14 years in the big leagues.

Merriam-Webster also added "heart-stopper," which is often used to describe close games, and "swole," which it defines as "extremely muscular." Another addition was more nuanced: "Oche," which is the line that a player must stand behind while throwing in darts.
