The act of scissoring, clit-clatting, bumping fur, polishing mirrors, or tribadism when two women rub vulvas to stimulate each of them simultaneously. A lesbian sexual practice. It's the lesbian form of frott, which is the male practice of rubbing genitals against one another.
"Scissor sisters" is a common position for train spotting, and the band Scissor Sisters was named after this practice.
