poppycock

This term carries a dismissive, slightly old-fashioned tone, often used to reject a claim as absurd or blatantly false. It suggests not just an error in fact, but a lack of substance or a deliberate attempt to deceive through foolishness. As an uncountable noun, it functions like the word "nonsense" and cannot be pluralized or counted with numbers. One does not refer to "three poppycocks," but rather "a load of" or "some" poppycock.
