Username Confusion

I was trying to change my Minecraft name and saw Aeolus ( Greek god of Winds) was available and I went to change it to that, but it said I can't change my username to something that might be offensive, and then I misclicked and changed my name to Aeozaa  but I'm just confused to why Aeolus was considered offensive?? I'm just sad because it's a cool name and I can't get it anymore because I'm on 30-day cooldown ;-;
