More formally known as a 138, it's a sexual position involving 4 people, two performing a standard 69, two behind them on either side using their...backdoors. Its name comes from 69*2, or 138, because it's essentially two 69's, possible position during a fourgy.
"Man that fourgy went crazy when Sarah and Vanessa started a 69 and then we joined in to make it a 138!"
"Yup."
