"Fifty Shades of Grey" - loom bands for adults

I was driving in my car with the kids yesterday and an ad came on the radio for the new "Fifty Shades of Grey" movie. 

The ad said: "This movie is a global phenomenon...".

My 10 year old daughter asks: "What's that movie about"?

I say (thinking fast...) "It's about relationships." 

"Can we go see it"? she asks.

"No, it's an adult movie." I say.

"Is it good"?

I say, "I read a few pages of the second book which a friend lent me - and it was rubbish - so poorly written. It's just a fad." 

My 8 year old son pipes up: 

"So it's like loom bands for adults?" 

"Yes." I say, "Exactly!"
