A Glass in the Hand

We've all seen this before. Perchance the character Does Not Know His Own Strength. Maybe he's entering a Heroic BSOD. Perhaps her Berserk Button has just been pushed. Whatever the reason, one thing is certain: that glass in their hand doesn't stand a chance.

Next thing you know the character has clenched the glass (or other breakable object) so hard that it shatters in their hand. Depending on the mood, realism of the work and the thing that broke, there may be a cut to a dramatic closeup of blood dripping down from the hand that got cut on the shards. If the character is mad enough they're likely to not notice the bleeding, which might be a good sign that it's time to start running away really, really, fast.

What shatters doesn't have to be a cup; it doesn't even have to be made of glass. It can be a metal can being crushed, or paper being crumbled unconsciously. The important thing in this situation is the distress of the character which caused them to inadvertently crush whatever they were holding. A purposely snapped pencil is a common way to show Suppressed Rage, especially when it becomes personal.

This trope can be used to heighten drama or, in the case that the character breaking the glass is unscathed, played for comedy.

A subtrope of Dramatic Shattering. Truth in Television under certain (painful) circumstances, but usually invokes the Soft Glass effect. Result of Rule of Drama, or possibly Rule of Funny, depending on the mood of the scene. Intersects with Knuckle Cracking. Geometric opposite of Drop What You Are Doing.

Anime & Manga

 * In Death Note, Light, acting as L, "advises" Near to escape from a situation Light himself created to trap him. While smirking. Near crushes the toy in his hand at Light's brazenness in barely even trying to hide his satisfaction.
 * Non-glass example in Bleach. When three of Barragan's Fraccion are defeated, he crushes one of the baubles on the sides of his makeshift throne, showing that he is quite pissed.
 * Roberta does this with a beer mug -- holding just the handle -- at the Yellow Flag in Black Lagoon, one of the few hints we get that she's an utter Badass before she breaks out the kevlar-lined Parasol of Pain and starts blasting people to hell. It also doesn't hurt her hand because she's wearing gloves or, more likely, because she is that Badass. And, as the next episodes show, this is the bottom of what she can go through unscathed.
 * Dragon Ball Z
 * Vegeta's scouter suffers this fate in the infamous OVER NINE THOUSAAAAAAAAAAAND scene.
 * Much later, Jeice does this to his scouter after reading Vegeta's Power Level.

 * Geki Hyuuma crushing his communicator is a Running Gag in Gao Gai Gar.
 * Shinn Asuka does this at least three times with soft drink cans in Gundam SEED Destiny.

 * In the anime episode covering the unveiling of the Nekoken, Genma does this while lamenting over how his son has suffered by having learnt the technique in question, crushing the glass he was drinking from (bloodlessly) while weeping over how you "just can't save a child from himself". The Hypocritical Humour here, of course, is that Ranma never wanted to learn the Nekoken -- Genma was the one who repeatedly wrapped his son in fish and hurled him into a pit of starving cats until the trauma gave him a phobia that could induce a cat-like split personality if he got too frightened.
 * In both anime and manga, when Akane has "traded" Ranma to Nabiki, she at one point hears what she thinks is Ranma entering Nabiki's room, which is right next door, and does the "listen through a glass against the wall" trick.

 * An occurence from the last book of the manga: Mousse, Ryôga, the Jusenkyô guide and his daughter Plum are spying on Ranma and Shampoo through a wall, Mousse using the old trick of putting a glass against his ear. When he hears Ranma asking for Shampoo to take off her clothes (a ploy to steal some of the Phoenix people's magical eggs, but Mousse doesn't know this), the glass between Mousse's fingers cracks.
 * In Shaman King, Tao En seems like a nice guy, right? I mean, he's stroking a panda's head. Then when he gets riled up... well, you know... this trope... Complete with Lampshade Hanging as he tosses the now decapitated panda aside. And yes, the panda felt it coming. And because he has the power to animate "Chinese zombies", the same panda makes an appearance at his lap again a few weeks later.

Real Life

 * During the making of Genesis' epic "The Lamb Lies Down on Broadway", band member Steve Hackett was reportedly so tense that he succeeded in this, severing a tendon in his thumb in the process.
 * One of the challenges in designing prosthetic hands and grippers is avoiding this trope. It's funny when your manipulator's force feedback sensors fail and you squish a glass. It would be less funny if you were shaking someone's hand at the time.
