darting to and fro

Darting to and fro is a cliche which means to move from one place to another and back again, often in a repeated rhythm. Darting typically means to move extremely fast from one place to another. Darting to and fro is most commonly heard in songs as well as in childrens stories and rhymes but it is also sometimes spoken in general, everyday conversation as a way to explain something going back and forth and back again.
