My dear female friend is [name_m]Mars[/name_m]! It is a nickname on her but she uses it exclusively because she doesn’t care for the full name. She generally gets a positive reaction. [name_m]Mars[/name_m] [name_u]Bar[/name_u] is a candy in the US as well and people sometimes refer to her that way affectionately, it’s not really a source of teasing.
[name_m]Mars[/name_m] [name_f]Io[/name_f] --> [name_m]Mars[/name_m] [name_f]Clio[/name_f]?
[name_m]Mars[/name_m] [name_f]Leocadia[/name_f]?
I spent a few minutes looking at names of kinds of cactus for potential middle names and they’re not very inspiring : /. But, maybe if you look longer you’ll find something?
[name_m]Mars[/name_m] Saguaro is pretty cool, except for the S’s sliding into each other, but that’s not the worst. [name_m]Mars[/name_m] [name_m]Arroyo[/name_m] evokes thoughts of cacti to me. For tundras, besides just tundra, there’s maybe Taiga and Ellesmere, like Ellesmere island.
