I guess there's no polite way to ask that question. I don't think any names are white trash - or trash for that matter. I would look up "Most Hated Baby Names" instead. Plenty of people have complained about names being too "trendy", having strange spellings, being vocabulary words, etc. Here are some lists for reference:

You will see consistent results, names that appear in more than two lists. I hope this helps. Have a nice day.
