A Glasgow smile (also known as a Chelsea smile, or a Glasgow, Chelsea or Cheshire grin) is 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.
The act is usually performed with a utility knife or a piece of broken glass, leaving a scar which causes the victim to appear to be smiling broadly.
