Viki was a name given to Wikipedia.;
The name was given when they pronounced Wiki incorrectly during the early seasons and has not been said by Rhett & Link recently. It faded out of popularity or they forgot about it.
The Girl Edit
No info on the girl, or real name is known. Nobody knows where Jason got the picture, for they only used it when Jason was the only member of their crew, in seasons 1-about two thirds of 3.
