A trio of three people, whose first letters of their first names consist of an "A", a "C", and a "J." JAC is typically awesome, exuberant, and quirky. If crossed, JAC can become vicious, manipulative and even violent. Everyone wants to be a part of JAC, but can't be.
I wish I was part of a cool trio like JAC.
JAC is so much better than ZAC.
