I had a few quick ideas, almost all of which are pretty weird lol.
Some decent ones I've got are:
• Nobby (like the house elf from Harry Potter, and imagining you as a house elf made me literally choke on a marshmallow lol)
• NobIsImportant>:d (kind of long but I like it )
• Dyim (I don't know how it would be pronounced; up to interpretation I guess lol)
• Odi / Nodi ( Idk, this one just seems cute and matches your personality )
• doorNob ( No explanation needed lol )
These are all goofy but I like them so yeah xD
Luv u <3
