‘A load of codswallop is an informal way of saying ‘lot of nonsense’; the origin of the first element of the word is sometimes said to be the name Hiram Codd who, in 1878, invented a bottle of fizzy drinks; this theory has not been confirmed. The element wallop may be from a colloquial use of the word from the 1930s for ‘beer’ or any alcoholic drink.’
