Well, I was going to wait for a bit but I never know when those flashes of brilliance in my head will fade away. So, some background first - I've been spending way too much time reading way too many articles about the Empulse and one theme that keeps resurfacing is... ahem ... sex.
So, with that in mind, I imagined the riding position and my first thought led to my suggested name for that part of the Empulse:
The Spoon.
Hey, it was either that or "Ms.B's arse"
