Obsidianize
A silly nickname for a girl who’s named after a crystal. It’s like giving a crystal a name and then giving it to a girl.
"My code name is Obsidian, which is just a fancy way of saying I’m named after a crystal."
Tweet: "Code name Obsidian? More like I’m a crystal with a bad attitude."
DM: "They named me after a crystal, and now I have to live with it."
