Bloxxa is a word Roblox kids use because both Roblox's admins, and their mommy won't let them scream the n word in video games. It is only racist if you are a minecrafter or terrarian. Only a real bloxxa may use this word.
Dirkman: "Wassup my bloxxa?"
Mario: "Not much my bloxxa. Just shot someone with my ro-gun"
