shack
n.— «I could see the bombs fly to the target on the FLIR…one second…Direct hit. “Shack!!!” I shouted over the radio. (That’s one term we picked up from our Air Force friends.) My wingman achieved the same results.» —“Desert Fox: The third night” by Ross Roberts United States Naval Institute: Proceedings Apr. 1, 1999. (source: Double-Tongued Dictionary)
