How do you refer to your neighbors without names?

Inspired by tennesseejac’s question!

Since we don’t know the names of the neighbors we tend to refer to them by obvious identifying characteristics. We would be horrified if they overheard our descriptors and probably so would they. It’s quite rude, but also the easiest and fastest form of identification. Do you do this or do you stick to names only?

We only know the name of one neighbor and two of us do actually use it. And the other two are constantly saying, “Who?” Which makes sticking to the other form easier.
