BTW, 'bollocks' isn't generally used that way in English
Funny story... since 'bollocks' isn't used in American when the Sex Pistols first album came out most people didn't understand the title.... (and/or thought it was a british way of saying bvllsh|t which I guess.... makes some sense).
I don't remember when I learned the anatomical meaning of the word but it was probably after moving to Poland....
the british meaning of 'fanny' also came as a surprise (since it only refers to the buttocks in American).
