Contrapposto is a term from art theory referring to a standing pose where most of the weight is shifted onto one foot, allowing the shoulders and arms to be twisted off-axis from the hips and legs. In layman's terms: hip out poses.
Tutorials (in Japanese) for drawing this type of pose can be found in post #339199 and post #1608647.
