The 11th edition of the Merriam-Webster's Collegiate Dictionary, published in 2012, credits Carter, who rarely used profanity, with the first recorded use of the term "f-bomb."
Carter died on February 16, 2012, at the age of 57. Nine days later, the Mets announced that they were adding a memorial patch to their uniforms in Carter's honor for the entire 2012 season. The patch features a black home plate with the number 8 and "KID" inscribed on it. On the Mets' 2012 opening day, the Carter family unveiled a banner with a similar design on the center field wall of Citi Field.
The NHL's Montreal Canadiens, who had purchased the Expos' mascot Youppi! and hung retired numbers in its arena after the Expos' relocation to Washington, paid tribute to Carter by presenting a video montage and observing a moment of silence before a game against the New Jersey Devils on February 20, 2012. All Canadiens players took to the ice during pre-game warm-ups wearing number 8 Carter jerseys, and Youppi! appeared wearing an Expos uniform. In addition, Youppi! wore a patch on his Canadiens jersey featuring a white circle with a blue number 8 inside it for the remainder of the season.
At Carter's memorial service, on February 24, 2012, Expo teammate Tommy Hutton made note of Carter’s deep faith. The three loves in Carter’s life, Hutton said, were his family, baseball and God.
