balderdash

This term carries a strong tone of dismissiveness and often implies that the nonsense being spoken is not just incorrect, but absurd or intentionally deceptive. It is more colorful and emphatic than the word nonsense, often used to shut down an argument by labeling it as completely devoid of logic. As an uncountable noun, it does not have a plural form and cannot be counted with numbers. To quantify it, one must use partitive constructions such as a piece of balderdash or a load of balderdash.
