foolishness; foolish talk. Come on! Don't give me all that stuff and nonsense! I don't understand this book. It's all stuff and nonsense as far as I am concerned.
Utter foolishness or absurdity, as in Stuff and nonsense, of course I can pack a suitcase. Often used as an interjection, this idiom employs stuff in the sense of "rubbish." It was first recorded in 1749.
