cut the cackle
colloquial phrasal verb

- stop talking aimlessly and come to the point

(Oxford Dictionary)

Experts think there may be a connection between cackle and the Middle Dutch word for jaw (kake), but it's most likely imitative, a word that sounds just like the noise it describes.

Cackle is a verb that means to let out a loud and unpleasant laugh or to talk in a cackling manner. It's also used as a noun to describe a shrill, loud and usually annoying sound, typically laughter, that resembles a cackling hen.

The expression "cut the cackle" refers to aimless talking that seems to go on forever. And by adding "cut" meaning to stop in this context, it forms an imperative to tell someone to shut up and get to the point of the discussion.
