I've used Monkeymillion for years in games. It's a reference to the infinite monkey theorem. A million monkeys banging on a million typewriters for infinity would eventually, purely by chance, write the entire works of Shakespeare. It's kind of self deprecating. I first picked it playing unreal tournament on PC 'back in the day'. It was because I was rubbish and doing well was likely to be just random luck! I also like the way it sounds :)
