Bollocks

Bollocks is a vulgar English expletive used to express disbelief, contempt, or dismissal. It primarily refers to testicles and is often used in a similar manner to the word "nonsense" or "rubbish". Its origin is believed to be from the Old English word "bealluc," meaning "little ball."

The word is considered highly offensive in many contexts and is rarely used in polite conversation or formal writing. However, it is frequently encountered in informal speech, particularly in British English, and its usage can range from mild frustration to strong anger. The term can also be used as an adjective, for example, "bollocks decision," meaning a foolish or incorrect one.

While its literal meaning is anatomical, its idiomatic use is far more common. It can be employed to reject an idea, a statement, or a situation perceived as absurd or untrue. For instance, someone might respond to an unbelievable claim with a simple "That's bollocks." The word's impact stems from its vulgarity, lending it a strong emotional charge.
