foot fault
n.— «Telstra suffered a judicial humiliation when it was constrained from making false and misleading statements about charges for its services and in what might be regarded as another foot fault, it was forced to give refunds to customers who were overcharged. Some little mistake that. Just $45 million.» —“How The Big End Of Town Makes Its Own Rules” by John Gilmour Sydney Morning Herald (Australia) Mar. 17, 2001. (source: Double-Tongued Dictionary)
