Do you have a name for your cup(s)? What about a nickname or a title? Does it have anything to do with the brand, color, or how you acquired it?
If this is an item we'll own for many years, why not name it to make it more familiar?
My smoky gray Fluercup is named Shropshire, but I usually call it my "plug" because I wear it for 12 hours on light days.
