Yeah, "box standard" is the correct saying and another popular corruption of a "saying" is "damp squid" instead of "damp squib". I thought "Dogs Bo**ocks" was a crude version of "Cats Whiskers", but I like your explanation betterLove the term "Bog standard", did you know that it derives from mechano, they did a box standard and a box delux, the term dogs b*******s also came from this, dox belux

PS ….. I was bought up in the Black Country and can still fluently communicate in Black Country dialect so my grasp of the English Language can be best described as a bit dodgy
