So let's talk nonsense.
Now I don't mean nonsense words; I mean words for nonsense.
For example, I hear "rubbish" used in British English for nonsense; while here in the US my experience it that rubbish is a seldom-used synonym for trash or garbage and not much else.
I've also heard "bollocks" from Brits in generally the same usage. I'm not certain -- is that bovine in origin, and thus of the same extraction of the common US "bull(suffix)"?
Along those lines in the US is often "crap" (BS in origin), "quatch" or "qvatch" (Pennslyvania Dutch -- German or Yiddish in origin), etc.
