A broad category of motion lines that includes lines that surround the contour of a character, or object. These lines may denote positions where part of a body, or object once was, or help describe behaviors of certain areas of the body that would be difficult to depict otherwise such as twitching, or shaking. Concepts that also tend to fall under this umbrella are lines that represent expanding, or shrinking.
