Funny why did you choose your username?

I have 2 variations of my name, Apaokz and apox_o.
I came up with Apayokz during a TF2 jailbreak game, trying to be cool with a really unique name. I decided that Apayokz made no sense and then changed it to Apaokz.
After almost a month of people pronouncing it "aye pox", i switched to apox_o. apox offical, and there ya go.
