nonsense

This word carries a strong tone of dismissal or irritation. It is used to shut down an argument or a claim by labeling it as logically impossible or ridiculously false. While it can be used playfully in a lighthearted context, it often signals a complete lack of respect for the validity of the statement being addressed. In a social setting, calling something nonsense is more aggressive than calling it a mistake. It suggests that the speaker is not just wrong, but that their words are devoid of any rational value. It is frequently paired with intensifiers like absolute or utter to emphasize the total absence of logic.
