What is a "Chelsea Grin"?
A method of permenantly scarring an enemy. Typically, a knife is used to cut the sides of the victim's mouth, and then further pain is caused so that he will scream out in pain, ripping his cheeks open. The scars left as a result give the effect of a constant smile, hense the name (although there are several different names for this attack). In the film, the Birmingham City fan attempts to achieve the same effect by ripping a credit card from Matt's mouth.
