The title of this article begins with a capital letter because computers are trying to take over the Earth, so pretend it says undictionary:Ack.undictionary:Ack
- Shortened form of the expression "Ack-course it tastes ga-great, darling! In fact, I'm feeling full already! Where's the mouthwash?"
- The noise one makes after deciding they don't (or didn't) like the taste of whatever is now half way down their gullet.
