Angie is something I've been called since I was little, my real name (Evangeline) is too long and flashy. I use Angie R. for pretty much everything, so why not as a Fakku username?
Siiaxxx I picked this name cause of a game and I thought the character Saïx acts as one of the "nobody-like" of the whole organization, And I thought it would be cool to be like him and be a nobody on the forums just show up every now and then but eh oh well.
My username is from the Japanese Video Game Itadaki Street. E series finally made its debut in America year 2011 in November or December with the Wii Title Fortune Street. Fun game, so happy for the release.
When I was a lurker, I played Ragnarok Online, and one of my characters was called Mello-- who was named after the one character from the Death Note. I was a huge fan at the time, so I guess the name kind of... stuck.
I've been using my username ever since I made my first e-mail address and I've never had any reason to use a different one (even though in some games I normally choose a cooler name). As for what it means... well the U,T are my initials and PM means pokemon master and I mixed those letters. Yep, I was young and loved (and still love) pokemons too much :)
My username it's only because of a random word that came from my head long ago, it sounded interesting for me and here i am now. There's not so much of a deep story or something that made me pick this username xD
