Yeah, I've met a La-a too. It baffles me that that must mean that someone heard of someone named La-a and thought, "that's so awesome!"

And more than one person, at that...
These are less inflammatory and are actual names, but I hate the names Myrtle, Ethel, and Mildred. I just see a short 80-year-old woman with white hair when I read or hear them and I would never name a child any of those names. I feel similarly about Dolores, but I would also see the Harry Potter character
And then there are pretty names that I could never use. I knew a Peyton once and every person around my parent's age would get a funny look on their face and start talking about how they could never name a child Peyton because of Peyton's Place. Which I haven't seen, so I don't get the reasoning behind it, but I've heard it so many times that I now have it firmly in my mind that I should never name a child Peyton

Lolita is a
beautiful name that I would never feel comfortable using, though I wish it didn't have that connotation.
