A game lesbians often play when bored or unamused. Similar the children's game "rock, paper, scissors", but instead refers to "rock" as fisting, "paper" as fingering, and "vagina" as scissoring.
Lesbian 1: "I'm Bored. Ellen DeGeneres isn't on, and I've already read the Feminine Mystique three times."
Lesbian 2: "Might I interest you in a game of Rock, Paper, Vagina?"
Lesiban1: "Sure! Let me just go make a sandwich first..."
