MOAC
n.— «Thorne said IED explosions can leave large craters—some as big as 80 feet wide. He said the massive holes are commonly referred to as MOACs, or Mother Of All Craters. “Sometimes they are four lanes wide,” he said. “It will take all night to fill it.”» —“After the blast” Batesville Daily Guard (Arkansas) July 3, 2007.
