Odds and sods and all that. Drobiazgi as they say in Polish. What an odd phrase. I might also talk about words like thingummy, thingamajig, whachamacallit all words like that. Every languages possesses words and phrases which – on the surface – mean nothing at all but in reality are important discourse devices, fillers that allow one to discuss abstract notions or non-signified objects with a generic tag. Brilliant!
