Okay, this has nothing to do with the usual subject matter of this blog, but it was far too amusing not to post. A long time ago my family started looking into the origin of the name Polaine and found Poulain de Liege from Belgium. There are many spellings of the name, but a common Medieval ones are Poleyn (a part of a suit of armour), Poulain (French chocolate) and Poulaine (a type of very pointy shoe).
It was a name for a young buck; it is derived from the Old French word poulain, which meant colt. This nickname would have been given to a person given over to friskiness and possessed of a certain nervous energy in much the same way a young horse is.
So, there you go, young stud.
