be twiddling (one's) thumbs
To be waiting idly because one cannot take action or has nothing to do at the moment. Although "twiddling one's thumbs" is an actual gesture (in which one's fingers are interlaced and each thumb is brought over the other in succession), the phrase is usually used figuratively. Oh, I'm just twiddling my thumbs in the ER, waiting for someone to give me an update on Claire's condition.
be twiddling your thumbs
If you are twiddling your thumbs, you are waiting with nothing useful to do. I'd far rather be cleaning than twiddling my thumbs waiting for the boys to wake up. There is a lot of team work too and no one is ever left twiddling their thumbs.
