[2] One occurrence of CBM can be observed in a left rock (adlib) turn in American Foxtrot.
As the leader takes their second step (the second "slow"), CBM occurs as the right leg moves backward and the left side of the body moves backward, causing the body to begin rotation to the left.
Similarly, as the follower takes their second step (the second "slow"), CBM occurs as the left leg moves forward and the right side of the torso moves forward, causing the body to begin rotation to the left.
An exaggerated CBM is the basic of some specific dance moves, e.g., Chicken Walks in Jive and East Coast Swing.
The term is slightly verbose in an attempt to make it self-describing and to stress the similarity of the dancer's feet position with respect to the body as if a step with CBM was performed.
