I got my nickname for these forums when MGS2 was about to be released. I was so disappointed that Meryl Silverburg wasn't going to be in the game, so I decided to use her name as a memory of her. It just kinda stuck now and I can't imagine me with another nickname on these forums.
Other nicknames I use for other forums:
wayneright- The last name of one of the main characters from the anime, The Big O
fruitsbasketfan- I'm a huge fan of the anime Fruits Basket, so I came up with it.
furubalover- Again, another Fruits Basket name.
Yes, I'm boring, I know...
