I generally have a working name for each project but rarely a fancy name, like right now I'm doing the "purple quilt" project. That's about the extent of my usual creativity as I look at the Dog quilt, the Halloween quilt, and the Valentine's quilt...
I'm finishing up one that is made of the traditional Flying Square block, I'm calling it "Not Quite Y2K" because I'm finally using my 1k or so of 2.5" Y2K squares along with some duplicates so it isn't Y2K in either fabrics or year. My fanciest quilt name was probably "Winter Dreams of Summer Skies" which was a broken dish design using black and about 20 shades of blue, and yes, pieced during the winter.
