Bollocks BO-ləks is a word of Middle English origin, meaning "testicles". The word is often used figuratively in colloquial British English and Hiberno-English as a noun to mean "nonsense", an expletive following a minor accident or misfortune, or an adjective to mean "poor quality" or "useless". Similarly, common phrases like "Bollocks to this!" and "That's a load of old bollocks" generally indicate contempt for a certain task, subject or opinion. Conversely, the word also figures in idiomatic phrases such as "the dog's bollocks" or more simply "the bollocks", which will refer to something which is admired, approved of, or well-respected.
