Smells like a hoax.
There are several “baby name” urban legends out there, so it could be a hoax. One in particular, I’ve had people swear up and down they had seen it for themselves but I’ve heard it over more than 30 years and 3 different states. ‘
I have, however, encountered plenty of names most people would never choose. Nothing parents would name a child would shock me. Names like Cupcake, or Sangria. Or names with funny spellings, like Conswaylow. A few years ago Nevaeh (Heaven spelled backwards) became popular. And then there are totally made-up names.
Years ago I was admitting a child, a baby, to the hospital. His name started with a Qu followed by 8 or 10 assorted letters; I had no clue how to pronounce it, so I decided to be clever. I asked the mom, “Well, what do you call him?” The answer: “We call him Boo!”
