When I am not pontificating on Thorntree, I work as a volunteer docent at a history museum. Mainly, I give presentations about the Califonria Gold Rush to 4th grade students (9-10 years old). I've been revising my spiel to include some language stuff. For instance, when explaining how the use of mecury in gold mining damaged the environment, I digress into the Mad Hatter, how "mad" means "crazy" in British English and how the use of mercury in hat making didn't do much for hatter's brains.
Recently, I've begun to include info on how the early reports of gold were disbelieved. "Humbug!" said one newspaper reporter. I'm trying to find a good, short defintion of humbug" to use with the kids. This +humbug+ is 19th C. slang for a hoax, bullshit, utter bunkum. I can't use +bullshit, BS+ or even +bull,+ without risking the wrath of parents and teachers. +Hoax,+ I've discovered, is not a word these kids usually know. +Nonsense+ or +baloney+ don't quite have the connotation of a tall tale put out by some hoaxter. I'm not even sure today's kids know the term +baloney or if they do, would consider it hilariously archaic.
Any ideas what current US 10 year olds would use for this notion? Or a word that at least conveys what I want?
