Turning or rotating something aimlessly with your fingers; fidgeting or wasting time.
From 'twiddle,' which likely evolved in the 1600s from onomatopoeia combined with 'diddle.' The exact origin is uncertain but related to 'twirl' and 'twist.'
The phrase 'twiddling your thumbs' originated as a real gesture of impatience and boredom, and it became so famous that it's now more about the meaning (wasting time) than the actual physical motion!
