I enjoy name symbolism.
If you sound out my username, Arvayn, it's supposed to sound like "are vain".
When I signed up here, it asked me for a username and I got stumped. "Why do I need a name?", I asked myself. "This is pointless.", I thought.
There is a colloquialism: you can say that something is being done "in vain", which means that it is ultimately pointless and won't accomplish anything of importance.
So... Arvayn. Literally "pointless username".
