This reminds me of a parallel expresssion in mycology: > "Little brown mushrooms" (or LBMs) refers to a large number of small, dull-coloured agaric species, with few macromorphological uniquely distinguishing characteristics. > As a result, LBMs typically range from difficult to impossible for mushroom hunters to identify. > For mycologists, LBMs are the equivalent of LBJs ("little brown jobs") and DYCs ("damned yellow composites") that are the bane of ornithologists and botanists, respectively. https://en.wikipedia.org/wiki/Mushroom_hunting#Little_brown_mushrooms https://en.wikipedia.org/wiki/Mushroom_hunting#Little_brown_... https://en.wikipedia.org/wiki/Damned_yellow_composite https://en.wikipedia.org/wiki/Damned_yellow_composite
