Recently tried to use the word 'gosen' (as stated many times by our favorite heroes to mean trash or crap) around my Chinese co-workers; I was met with baffelment. Looked it up and yes, Serenity is gosen (arcane feelings of more Japanese staff defense?)

Anyone with better Chinese please chime in, my boss knows Mandarin and Fujaineese but mayhaps it means something else in another dialect.
