[heathfield]

Wallop is, of course, strong ale. Mr Codd produced bottled soda water, worthless if you want to get p*****d. So 'codswallop' means something worthless, these days usually applied to a remark or statement that is deemed to be incorrect or untrue

This was on the "balderdash and piffle" programme on the BBC but they couldn't be sure which explanation was correct.
