Interesting, especially as so many of you know one. It's a relation who is trying a bit too hard (IMVH-unasked-for-and-unreasonable-O) to be different and have a name that no one else will have. Personally I hate it, but then I'm from the boring traditional names camp.
It's worse because her husband is really into motorbikes so my (and most people's, I'd guess) reaction is that they're calling him after the motorbike.
