The origin of this wonderful word is unknown but it was certainly in use by the time of Shakespeare. At the time it meant froth or a frothy liquid or even a jumble of liquids e.g. milk and beer. Only in the latter part of the 17th century did it become known for its current meaning.
This is an Americanism
from the early 20th century and comes from baloney the sausage. The

The first use of the word was as theatre slang in the 18th century when a line or speech in a play was designed to elicit ["trap"] applause ["claps"] from the audience. Our usage of it comes from the 19th century.

At that time Wallop was a slang term for beer so Codd's Wallop was the rather rude term given by drinkers to Mr Codd's mineral waters and soft drinks
From the wash [swill] given to the swine [hog]. In 1440 it was spelt as hoggyswasch! The first written record of the modern meaning is seen in 1712.
Derived from twattle meaning to talk foolishly. A twattle basket was a chatter box.
