bosh
Preserved but no longer current.
Nonsense, stupidity.—Gipsy and Persian. Also pure Turkish, BOSH LAKERDI, empty talk. The term was used in this country as early as 1760, and may be found in the Student, vol. ii. p. 217. It has been suggested, with what reason the reader must judge for himself, that this colloquial expression is from the German BOSH, or BOSSCH, answering to our word "swipes."
Era: ca. 1874 (Victorian)
