Glasgow smile
a wound caused by making a cut from the corners of a victim's mouth up to the ears, leaving a scar in the shape of a smile
A Glasgow smile (also known as a Glasgow grin, Anna grin Cheshire grin or Chelsea smile) is a nickname for the result of cutting a victim's face from the edges of the mouth to the ears. The cut – and the scars it leaves – form an extension of what resembles a smile. Sometimes further to hurt or even kill the victim, he or she would then be stabbed or kicked, most notably in the stomach (or in case of kicking, the groin), so that the face would be ripped apart when the victim screamed. Mutilation of this kind is commonly inflicted with a utility knife.
