It’s Major League Baseball playoff season, so it seems like a good a time as any to provide the definitions for all those funny terms that the players, managers, and broadcasters pepper into their conversations about the national pastime.

Hot stove. The offseason, when fans and analysts obsess over free agency and trades in anticipation of the new season. It’s as if they’re all standing around a hot stove to keep warm in the winter.

Flashing leather. A flashy or impressive defensive catch — as mitts are made of leather.

Bump. That’s the pitcher’s mound.

Southpaw. In the early days of baseball, parks were built in such a way that when left-handers were on the bump, they faced the south. A paw is a hand, so they were southpaws.

Around the horn. After the pitcher strikes out a batter, the catcher gives a hard throw to the third baseman, who tosses it to second base, and then first base just as quickly. Taking the ball around the horn is a way to stay loose and celebrate a job well done for the pitcher.

Get dirty. When a coach yells this at a baserunner, it’s an instruction to slide hard into their next stop.

Snow cone. A fielder may sometimes make the catch and the ball rests in the top edge of their glove, and it sticks out and resembles a snow cone.

Daddy hack. When a batter takes a powerful swing and misses altogether and almost falls over under the force of his own whiff, that’s a daddy hack.

Meatball. A slow, right down the middle pitch that’s easy to hit.

Uncle Charlie. A high-flying, sharpy breaking curveball that’s quite tough to hit.

Immaculate inning. It’s also known as a perfect inning and it’s exceptionally rare. It happens when a pitcher needs the nine minimum strikes to retire all three batters for all three outs.

Can of corn. An easy to catch outfield fly ball. It’s easier than a can of corn, in fact, which is apparently a very easy thing indeed.

Cheddar. A really fast fastball.

Moonshot. A home run that leaves the park and travels so far nobody can see it, as it if flew to the moon.

Cheerio. An umpire who maintains a tiny strike zone, like one as small as the inside of a Cheerio cereal piece.

Dinger. A home run.

Salami. A play on “grand slam,” which is a home run worth four runs, hit when the bases are all occupied.
