I can't get my head around some of the names that do and don't fit in with American tastes, and I've been trying for years, at a distance admittedly. But I deplore
Poppy though I really love the flowers. I'd rather name a child
Shirley than
Poppy! And I know someone with a young
Poppy (in the UK), and when I'm talking it's fine but when I'm typing an email my fingers take over and I involuntarily type
Polly every darn time.
I don't know if it's got anything to do with 'poppycock' but
Poppy just seems so limp and flaccid; and the etymology of 'poppycock' most emphatically doesn't help.
