Twiddly bits
From Wikipedia, the free encyclopedia

Twiddly Bits is an English slang term. From the word twiddly (sometimes spelled Twiddley); curly or decorative, esp. in an unnecessary way [1] and bit; a small piece or amount of something,[1] a twiddly bit is anything that is relatively small and trifling or elaborately decorative.
Twiddly is a commonly used word in British English, as in Roald Dahl’s The BFG, where the giant’s large ears allow him to hear absolutely every single twiddly little thing.[2] The term twiddly bit is applicable in almost any context and is commonly used to describe aspects of architecture, art, music, literature, fashion, etc.
