Right first of all this is not a wah. (However "wah" would be a suitable word for inclusion in this topic!) When I was in first time round - 1987-92 many of the terms used today were unheard of. Furthermore they seem to have no obvious origin in more common terms. For example: Bone idle is a common term in civilian life but has no obvious connection to the army slang use of "bone" meaning of "stupid." In more common parlance someone might be on their "Jack Jones" (Rhyming slang for "own"), he might "jack something in" (give it up, pack it in) but neither seems related to the army slang adjective "jack" meaning idle, lazy etc. Threaders? My best take on this given the context it's used in is from rhyming slang: Threadbare = Spare. Going spare = going Threadbare which has evolved into going or being Threaders. Back in the dark ages, having lots of fancy warlike kit was the "warry" look, we would have "warry" exercises although I recall that this wasn't universal. It was well established in the Midlands in the late 80s but was a new term in the North West in the early 90's. Now it has been superseded by Ally for which there are various suggested origins, mainly pointing towards "Ally Airborne".... wherever that started! Any thoughts on the origin of these or other slang words or uses?
