pell-mell

When things are messy, wacky, crazy, and all over the place, they are pell-mell — chaotic.

If your room is a mess, with clothes everywhere, it's pell-mell. If people are running in every direction and yelling, that's a pell-mell situation. Whenever things are out of hand, off the hook, and chaotic, it's pell-mell. Words with a similar structure and meaning are "higgledy-piggledy," "harum-scarum," and "helter-skelter."
