Im actually reading the laws for where I live on name changes and I have to have a surname anyways--you cant 1 name it here
I have the perfect solution.
Picture some bitch in a club...
Avesher strolls up to the bar, bitch looks at him and says "whats your name big boy"
You stare at her for a few seconds, then calmly and cooly say "Avesher. Team Avesher"
Bingo, your new name. Surname and all.
