Hi Sandra,

I don't know that particular expression so it probably means it's not Australian

It sounds like a variation of what is commonly used down here which is "Don't get your knickers in a knot". That expression means "don't let yourself get stressed / angry about something" (to the extent that it feels like your underclothes are all twisted up and uncomfortable).

All the best,
Noel
