Glasgow Grin

Go To
No points for guessing why they call him "Slit".
"Let's put a smile on that face!"
The Joker, The Dark Knight

When a character suddenly breaks into an ear-to-ear grin, it's a Cheshire Cat Grin. When this is permanently part of their facial structure, whether they're happy or not, it's a Glasgow Grin. It may have curlicues or stitches at the ends. This also happens a lot with puppets, intentionally or not.

Named, of course, after the Glasgow Smile, an act of violence (supposedly popular with Violent Glaswegians) in which a person's cheeks are sliced open starting at the edges of the mouth. Not all characters with a Glasgow Grin have been scarred; some of them were born with it. Generally, characters with Glasgow Grins tend to be evil, insane, or both. If it is a protagonist character who is not a villain, it also just shows that they are a somewhat dark character. It's sometimes known as a Chelsea Smile, in reference to the London football team, whose more violent fans were reputed to inflict it on people as a Finishing Move, or as a Traveller's Smile, also called "sourire de l'ange" (the angel's smile) in French.

Compare with Cheshire Cat Grin and Slasher Smile. Contrast Perpetual Frowner. An inversion is Mouth Stitched Shut. Sub-Trope of Facial Horror. Not to be confused with the "Glasgow Kiss".

  • There's an infamous ad for Durex condoms that shows a woman with bandages at the edges of her mouth (the implication apparently being that her recent partner's endowment was a little too big).

    Anime and Manga 
  • Attack on Titan:
    • The Female Titan opens her mouth so wide it splits so she can devour/capture Eren after defeating his Titan form. She pretty much redefines Body Horror.
    • Another well-known example is a titan that wears a permanent grotesque grin and can unhinge its jaw to bite, known as the Smiling Titan.
    • Holders of the Armored and Jaw titans receive scars resembling Glasgow grins when they stay in their Titan form for an extended period. The Armored Titan has one in its Titan form too, but it's a downplayed case as it's formed by his bony exoskeleton and is not a scar to begin with.
    • In the prequel Attack on Titan: Before the Fall, Ogre, a pure Titan has a significant case of this, which defies all logic as Pure Titans are usually pretty scarless.
  • Demon Slayer: Kimetsu no Yaiba: A pretty grotesque example with Obanai Iguro. It’s inflicted on him as a child due to his family worshipping a snake demon, and her wanting to make him more like her before she eats him. However, it’s also the reason he wears the mask/bandages.
  • Franken Fran:
    • The eponymous character has stitches going ear to ear. In her case, it's because she's an Artificial Human (the similarity of her name to Frankenstein's Monster is deliberate), so presumably her head and jaw come from different "donors".
    • An omake features a kuchisake-onna, a woman in Japanese legend who wanders around wearing a mask over her slashed ear-to-ear mouth and asking people whether she's beautiful. What happens after this varies, but it always includes the threat of her slitting your cheeks like hers, whether you say "yes" or "no" (the word she uses for "pretty" is a homophone of the verb form of "cut", which is why she will attack you if you say yes). The woman does her thing to a guy, but it backfires completely as it turns out her mouth is fetish fuel for him, and she ends up running away calling him a pervert.
  • Heinkel from Hellsing gets one of these toward the end after taking a sniper round through the mouth. She doesn't seem too bothered by it, but it makes her dialogue a nightmare to read.
  • Ichi the Killer: The deranged gangster Kakihara has cut cheeks that he let his fellow gang members inflict on him. His is interesting in that he kept the cuts in his cheeks from sealing together when they healed and scarred, so the slits are permanent.

  • In JoJo's Bizarre Adventure: Steel Ball Run, these are the aftereffects of Scary Monsters when turning from Dinosaur back to human. This sometimes happens to the Stand User, but each time it's creepy as all hell.
  • My Hero Academia: Dabi has one as part of his facial scarring.
  • Naruto:
    • While in the four-tails form, Naruto's mouth slits go further back than usual, though it healed after.
    • Kakuzu has most of his joints modified by his kinjutsu to come apart at will; this results in disturbing Glasgow Grin-like disfiguration of his face.
    • After injecting himself with Orochimaru's genes, Kabuto has a new snakelike form. In this form, he can open his mouth so wide it practically rips open. This results in clear cut marks on the sides of his mouth even when it's closed.
    • The Ten-Tailed Beast has naturally far-back mouth slits, better showing how it's filled with rows of jagged teeth.
  • The Perverse Puppet Chachazero of Negima! Magister Negi Magi smiles while saying the most twisted or acidic of things, if only for the fact that she was carved that way.
  • One Piece:
    • Doctor Hogback has stitches that extend beyond his permanent smile to encircle his whole face. It fits right in with his expertise of Frankensteinian assembly of corpses via stitching. Despite this smile, Hogback can express a full range of emotions via body language.
    • Absalom's mouth may be even worse since thanks Hogback he has entirely different mouth (a Lion's) stitched on to his face.
    • Katakuri's mouth aside from his massive fangs has two asymmetrical stitches on his cheeks. Katakuri ''really'' doesn't take kindly to his mouth being seen or talked about. As he kills the three chefs who see his face.
  • Joejoe of Toriko has what looks like stitches on the entire length of his mouth, which runs for the entire width of his visible face. Zebra has half of a Glasgow Grin — his left cheek is torn, exposing his teeth up to the wisdom ones. It might be intentional — he claims that it's useful for shoveling food in, and might be possibly useful for all his shout-based attacks. For a short time, Zebra's cheek was sewn together, but the stitches gave way quickly.

  • The Dark Knight: Instead of the character's traditional rictus grin, the Joker's mouth was apparently torn open, given the ragged, uneven scarring on his cheeks and lower lip.note  He gives two completely different explanations for how and why this happened, and tries to give Batman a third.

    Batman: No. But I know how you got these!

  • Godzilla:
    • The MonsterVerse version has a "born with it" variation, though it's only really visible when he opens his mouth to roar or use his atomic breath. Its design seems to be based off the similar "smiles" of many real life reptiles.
    • Likewise, the Godzilla of Shin Godzilla has a "born with it" version, due to his large and ragged mouth and the amount of teeth he has.

    Death grinned because, as has so often been remarked, he didn't have much option. But possibly he meant it this time.
  • Everworld has a Viking by the name of Sven Swordeater. Guess what his cheeks look like.

What happens after this varies, but it always includes the threat of her slitting your cheeks like hers, whether you say "yes" or "no" (the word she uses for "pretty" is a homophone of the verb form of "cut", which is why she will attack you if you say yes).

However, there are several third options for dealing with her, such as apologizing that you have to be somewhere else right now or saying you're neutral or ambivalent on her appearance.

  • Metal Gear:
    • It's only visible for a few seconds, but in Metal Gear Solid, Psycho Mantis sports a small, half-Glasgow grin on the right side of his face; its origins are unknown.
    • Raiden, of all people, seems to possess this in Metal Gear Rising: Revengeance. He had a similar but less noticeable example in the ending of Metal Gear Solid 4: Guns of the Patriots. The reason is, before the fourth game began, Raiden's body was replaced by an artificial cyborg version, leaving only his head sans lower jaw intact. That line is where his organic parts connect the cybernetic parts.
  • Mileena's new character design in Mortal Kombat X gives her a fully functional set of human lips, bordered on both ends by razor-sharp Tarkatan teeth that form a menacing grin. This was still not enough to make her ugly in the eyes of some players.

Judging by the state her wraith is in, they outdid her by tearing off her jaw.

    Western Animation 
  • The very first episode of Batman Beyond features a Joker pulling a huge knife on Terry and declaring his intention to "put a smile on his face". This is probably something Jokers do a lot.
  • Final Space: Invictus' demonic-looking astral form has a permanent, jagged-looking grinning shape for a mouth which never moves. It fits with how the Slasher Smile is Invictus' default expression when it's possessing a body, but what fully drives this trope home is that the grin is on Invictus' astral face even when it's pissed off.
  • In the Love, Death & Robots episode "Good Hunting", the bionic Huli jing prostitute Yan fights off the Governor of Hong Kong who was beating her, reaching into the sides of his mouth and ripping hard...

All this to get information from David, who knew nothing about what they were asking him about.
