What is the significance of these white oval stickers with letters on people's cars?

They usually have three letters on them. For instance, PLE or OBM ( not necessarily the exact letters) with a black oval outline and a white backround. What the h*** is that? It annoys me. Is it some secret society where only a***holes in big chevy trucks (that also have a sticker of calvin peeing on a ford symbol) can belong?

its a place that you've been, I have an OBX one, its from Outer Banks, its just an abbreviation of a place they went.
