I name my chars based on mix of letters or the start of things like .. mage human white arcane would be like Mahuwhar.
Or based on movies.
Or animes.
Or food.
If someone dares saying something .. their names is surely 100 times worse than mine .. because lets face the fact that only people with serious self-esteem problem would judge others by their name only or insult them because of their name .
All you gotta do is pity them .
