Yes this is a real procedure. Abdominal etching, which also goes by several others names such as ab sculpting and lipo sculpting, is a procedure a plastic surgeon by the name of Dr. Henry Mentz wsa the credited as pioneering in the early 90's. It involves using a special canula which is designed to shape and contour the fat above and around the abs. Tiny amounts of fat are removed around the patient's natural muscle contours. Depending on the body type the end result with either be a flat stomach or "six pack" abs. I believe other doctors besides Dr. Mentz do this now but I personally do not know of any.
“One popular new plastic surgery technique is called lip grafting, or "fat recycling" wherein fat cells are removed from one part of your body that is too large, such as your buttocks, and injected into your lips; people will then be literally kissing ass.”
