queef-scissoring
When two women are scissoring, one queefs into the other's vaginal opening. The second woman then emits her own queef adding to the volume of the queef. This continues until both vaginas are completely full of fishy air.
Female 1: "I'm really bored. Do you want to watch a movie?"
Female 2: "Only after we get some queef-scissoring done."
