A Glasgow smile 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. The practice is said to have originated in Glasgow, Scotland, in the 1920s and 30s.

In popular culture

In modern fiction, the Glasgow smile has become a characteristic physical feature of some incarnations of the Batman villain Joker, most famously in Heath Ledger's interpretation; the yakuza boss Masao Kakihara, from the manga Ichi the Killer; and the creepypasta character Jeff the Killer.
In music, it is the name of the band Chelsea Grin. Additionally, there is a Bring Me the Horizon song by the title of Chelsea Smile.
