Balderdash (n.)
1590s, of obscure origin despite much 19c. conjecture; in early use "a jumbled mix of liquors" (milk and beer, beer and wine, etc.)
Indeede Beere, by a Mixture of Wine, it enjoyes approbation amongst some few (that hardly understand wherefore) but then it is no longer Beere, but hath lost both Name and Nature, and is called Balderdash (an Utopian denomination) [...]
