A ZA moment is when you are right in the middle of a situation but STILL have absolutely NO idea what's going on and usually need it explained to you. THAT'S a ZA-moment.
She: "What book are you reading?"
He: "Book?"
She: "The one in your hands".
He: "Uh-ZA! Got me; it's an auto manual"

Y: Order?
W: Your meal. Have you decided?
Y: "OH! Uh, yes! Sorry! Had a ZA-Moment there."
