There's a thread on /r/aww where the OP had posted his dog Lolita, and everyone in it is convinced that no one could have a connotation attached to the name independent of the book/movie. Feels like it's just brainworms, but maybe I'm the only person in North America that hadn't really heard much about that book until recently.
It's a pretty well known book. Recently came more into public discourse after Epstein, for obvious reasons, but Nabokov is considered one of those "famous writers" all the same.
