MUJAK/M.U.J.A.K.
(Pronounced, "Moo Jack")
Made Up Job (for an) Ass Kisser.
A- Did you hear? "John Doe" was "promoted" to Club Operations Assistant.
B- "Club..." what?! That MUJAK position didn't exist a month ago! In other words, he's going to be "Jane's" personal ass-kissing errand boy and snitch. Watch your back!
