Not to stir up any poo, but sometimes it is easier to refer to all three species generically as "stripes". I do it all the time when on the Ohio River, or any other body of water with a mixture, just to keep the conversation simple. If asked, or when bragging about a specific fish, I will specify the species. Most people that understand the difference will ask if it was a white, striper, or hybrid as well.

I agree wholeheartedly that you must understand the regulation and know the species for the specific body of water that you are fishing. Not only can it cost you some $$$, but you can hurt a population of one fish if you think you have something else, i.e. keeping a bunch of small stripers at C-land because you believe that they are whites or hybrids.
