A brilliantly vivid New Zealand idiom meaning to go completely wrong, fall apart, or descend into chaos. When a plan, situation, or event turns to custard, it's not a minor hiccup — it's full collapse into a wobbly, formless mess, which is exactly what custard does when you don't follow the recipe. The phrase captures that particular combination of disappointment and absurdity that comes with spectacular failure. Widely used across New Zealand in casual and professional contexts alike.

The event was going fine until the sound system broke and the whole thing turned to custard.
Origin: A New Zealand idiom drawing on the image of custard — a substance that appears solid but collapses into an ungovernable mess — as a metaphor for plans falling apart. Editorial expansion authored on Slangora.
