Codswallop!

If something is a load of old codswallop it is nonsense or of no value. Where does this odd word come from?
One theory speaks of Hiram C Codd, who in the 1870s, went into business selling lemonade in green glass bottles with marble stoppers.
‘Wallop’ was a nineteenth century slang term for beer and Codd’s wallop is said to have become a disparaging term amongst beer drinkers for mineral waters and non-alcoholic soft drinks, such as Codd’s lemonade.
These days the word has no connection with beer and lemonade but is used to refer to anything of no value and is mostly heard in the phrase ‘load of codswallop’ meaning ‘load of hogwash’.
Another theory is that the word just sounded nonsensical and so was added to the list of nonsense words such as twaddle and bunkum.
It was definitely used in an episode of the UK television comedy show, Hancock’s Half Hour in 1959, but the writers say that it was already in use
