I give them all sorts of weird names. Most of them are pretty dull, come to think of it.
A purple & turquoise bargello ended up named "Turple and Purpquoise", just because that's how my mumbly mouth kept saying those words.
The quilt I was making for my husband as a gift ended up with the name "<redacted>", because I keep a list of quilts-in-progress and I didn't want him to see his name on the list.
A black, white & red D9P quilt ended up named "D9P150" - the "150" because my husband has synesthesia (he strongly associates colors with numbers) and this was a quilt he picked the colors for. 1 is black, 5 is red, zero is white.
A quilt with 72 kitty-cat blocks got named...."72 Kitties" (told you, dull!)
Most of them don't really get names, they're just listed in my journal as "rag quilt 1" or "crazy quilt 3". Super dull.
