Back in 2008, CBBC made this game called Adventure Rock. At that time, I usually used 'aspcc' as my username, which originated from my older sister taking the first letters of the first name of each member of our immediate family and stringing them together. However, Adventure Rock required a username be six letters or longer.

Before then I had played this Pokémon fan game. At one point in the game, I needed a password to see this old sage. The password ended up being 'goldrush'. With that being more than six letters and me already having a password, I tried to use that as my Adventure Rock username. However, that name had already been taken. The game offered a few similar alternatives, one of which was 'rush99999'. I chose that one and have been using it ever since.
