Bollocks

Although its modern usage is now a rather vulgar synonym for rubbish or nonsense as in, “what a load of bollocks”, this was once a perfectly acceptable word for testicles dating from at least the 13th century. Bizarre as it sounds; bollocks are mentioned in the Bible, specifically the Wycliffe Middle English version (c. 1382-1395). Leviticus 22:24. “Any beast that is cut and is taken away the bollocks, you shall not offer to the Lord.” This means that castrated animals are not suitable for sacrifice. Perhaps to spare puritan blushes, the King James Version of the Bible (1611) replaced the word bollocks with testicles.
