A derisive modification of the VGF member Saria Dragon's abbreviated name. STD is used to make reference to Saria Dragon's abnormal sexual relation with the VGF member Tub-o-troopa. Use of STD became commonplace after Saria Dragon and Tub-o-troopa had cyber sex in the popular VGF forum game, The Person Above Me.
Saria Dragon, or SD, just cybered with Tub on VGF. She's more like STD now.
