JAC

JAC is an abbreviation for “Just A Comment” - most commonly found on Facebook

If someone posts a message asking “Who’s up to go see a baseball game?” And someone may reply “JAC I love baseball!” The commenter is not indicating that they want to go see the game, but instead is just contributing a comment about their love of the sport instead.
