As for "codswallop", while it resonates happily with codlings, it seems in fact to have no genuine history prior to 1963, unless you believe it was a 19th century lemonade product sold in green bottles by a Mister Codd, which I do not.

However there is a really funny song (since this is a music site) about codswallop which can be found on this page.
