V Day or Vagina Day is a day established by Eve Ensler, author of the Vagina Monologues, to end domestic violence and sexual abuse of women. It is celebrated on Valentine's day and many communities put on plays from parts of the Vagina Monologues or additional stories related to orgasms, menarche, first sexual experiences, sexuality, molestation, rape, etc. They express what a vagina would say if it could talk. Proceeds from the plays go towards centers for domestic violence and rape preventions.

V Day, short for vagina day, is conveniently celebrated on February 14th, and is enjoyed by all. Many are unaware that when they yell "Happy V day", (intending to mean Happy Valentines day), they are really wishing the other person's vagina has a happy day.
