1-Acronym for Sexually Transmitted Disease, which is duh any disease you can get with any kind of sexual contact ie The Clap, Crabs
2-Ironically, could've been a group on WWE'S SmackDown! with Divas, Sable, Torrie Wilson, and Dawn Marie since their first initials spell that out
Ex1-Better wear condoms, you never what know STD you're gonna get.
Ex2-Imagine if Sable and Dawn Marie hadn't been fired and they and Torrie Wilson formed STD and said things on SmackDown! like "When you're lying in the middle of the ring and you feel that pain between your legs--you know you've just been infected by STD!"
