Nullonym
A placeholder name or title used when the real name of a person, place, or thing is completely forgotten, unknown, or irrelevant. Unlike a generic placeholder (like "thingamajig"), a nullonym acts specifically as a temporary proper noun to keep a conversation moving.
"Our driver's name is completely unpronounceable in my head.""Just use a nullonym so we can talk about where he's dropping us off.""Good idea. 'Captain Cruiser' it is."
