A strong, smart, sassy woman who is unafraid to speak her mind and stand in the face of opposition. Can be abbreviated as "VT."
Origin: On the Religion and Spirituality section of Yahoo Answers, a troll was flaming a female "regular," calling her "Jezebel," "Vile Temptress," and "Whore of Babylon." To show their support, several other women on the site changed their name to include "Vile Temptress" or "VT" and now it is an ongoing meme. There is a band, a pseudo-religion, and a sitcom in the making. The VTs, naturally, have many followers.
"She tore that fundie to pieces. What a Vile Temptress."
