Nassau and Suffolk counties have distinct identities, and the people who live in each area have special knowledge that tie them to their counties.
For instance, if you’re from Suffolk, you know how to pronounce Ronkonkoma, Hauppauge and Patchogue. And you've definitely searched for the "Amityville Horror" house.
So far, we've assembled -- with help from social media followers -- 21 signs someone is from Suffolk. Now you can help add to the list by adding suggestions below or emailing us at email@example.com.
Next up later this week: Signs you're from Nassau. Feel free to add suggestions for that list, too.
