The Swirl and Twist are sexual maneuvers that Ellen Tigh specialized in.
Ellen and a Cavil mention them briefly after a sexual interlude (TRS: "Precipice").
Later, a revived Ellen (now recalling her true involvement with the Cylons), asks Sharon Valerii of her relationship with the Number One individual Ellen calls "John," asking her if John taught her about the Swirl in an attempt to belittle John and his anger (TRS: "No Exit").
Notes
- In the podcast for "Precipice", Ronald D. Moore states that references to "The Twist" and "The Swirl" are a homage to a Seinfeld episode, "The Fusilli Jerry."
