Where are you from? I was pretty shocked to learn from chinese people that they thought the english euphemism for pornography was "blue". This is the first time I've seen someone use it.
I'm from Ireland and "blue movies" used to be a common term for pornographic films and I'm fairly certain that our British neighbours also used this terminology. However, while typing this comment it occurs to me that I haven't heard the term in many years and I suspect it has fallen out of fashion as Internet sites have taken over from sex shops (which really only arrived in Ireland in the mid to late 90s).
