Bollocks
"Bollocks" /ˈbɒləks/ is a word of Anglo-Saxon origin, meaning "testicles". The word is often used figuratively in 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, the common phrases "Bollocks to this!" or "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", "top bollock(s)", or more simply "the bollocks" (as opposed to just "bollocks"), which will refer to something which is admired, approved of or well-respected.
