I shall not niggle.

I shall not niggle.

There's something niggling me.

Just scratch that little niggle

So scratch that little niggle

Then I shall not niggle.

I shall not niggle. Can we depart this afternoon?

You won't get any niggle there about the food.

You dare tell me your position in this firm. You niggling little twit.

And it's left that niggling feeling ... in the pit of your stomach ...
