Yaw
From polycount
If you shake your head "no," this is yaw in action.
One of the three rotational axes commonly used to describe the rotation of an object. The term comes from aviation.
Most game engines count from 0 to 360 degrees, starting out pointed straight forward, turning clockwise and ending pointed straight forwards again. Straight forward is both 0 and 360 degrees.
