I always thought it was just "alibalah timmhya!"
so i didn't know why people quote 'livin a lie' except for Jimmy getting it wrong in cripple fight
but watching timmy 2000 again, in the first time timmy is on stage with the lords of the underworld, it really does sound like "livin' a lie"
in the same way as Trey does "livin' a lie" when "singing to old people" in the Season 2 intros (when he nearly lost his voice lol).
so there's some fresh info for ya!
