Intimidation Demonstration

When someone wants to show off how skilled they are with a weapon, martial arts, acrobatics, or just plain strength, they will do some sort of flashy movement to display their skills, such as juggling knives, twirling a sword, swinging their nunchucks, flexing their pecs, bending a metal pipe, or kicking and punching while doing flips. This is very common in fighting games and martial arts movies, as characters will want to appear Badass by doing some unnecessary cool moves before they fight.

Can apply to twirling around firearms, but not that type of twirling. Just don't confuse intimidation with a Dramatic Gun Cock.

Another variant is simply a demonstration of firepower and/or military capability. In Real Life, this is a common diplomatic tool—if you want to intimidate a country, conduct a military exercise with an aircraft carrier battle group in their general area. Or a nuclear weapons test.

A favorite move of Bruce Lee clones, Martial Arts Movie, and Artistic License Martial Arts in general. Is sometimes combined with a taunt or Badass Boast. Often finished off with a Bring It or an Asskicking Pose. If someone does this badly, it could be considered What the Fu Are You Doing? or Flexing Those Non-Biceps. See also Defeat by Modesty and "If I Wanted You Dead...". If a person crushes something in their hands for a reason other than intimidation, see A Glass in the Hand. Battle Strip and Pec Flex are related.

 * Played with in School Rumble. First, Karen scares off an attacker by absolutely disintegrating an apple just by squeezing it in one hand. Later, Lala does this to intimidate a few classmates, but Imadori, unfazed, claims that it's no big deal and does the same thing with a ripe banana.

 * The Hunger Games: One of the nuances of the training room is whether or not you show off your deadliest skill. The Careers (volunteers for the Games) like to let the other tributes know what they can do as a sort of boast.
 * This leads to in-universe Values Dissonance in The Dark Elf Trilogy. To dark elves, demonstrating one's superiority with a weapon to someone else, while leaving them completely unharmed, is an indicator that you have no intention of harming them and in fact wish to ally with them. When Drizzt tries this on a human, the response is one of fear.
 * In the Sherlock Holmes story The Adventure of the Speckled Band, Dr. Roylott, an ill-tempered and violent man followed his stepdaughter to 221 B Baker Street (where she had gone to consult Holmes about the death of her sister) to warn Holmes off by bending an iron bar in order to intimidate Holmes.

The Jovians thought they were humans.

Tabletop RPG

 * Dungeons and Dragons
 * 2nd Edition had a Non-Weapon Proficiency (non-core, but present in multiple settings and options) called "[Display] Weapon Prowess". If the user has an opportunity to show off and demonstrated his weapon skills successfully, it causes opponents to make a morale check - those successfully intimidated try to avoid fighting the character or will fight more cautiously (with attack penalty), depending on the circumstances. Since it's a performance skill much like juggling, it doesn't have impact on anything else, and does not affect higher-level characters.
 * In the Hero Game System this is covered with the "Presence Attack" mechanic. (You get bonuses if you do it really well).
 * Starblazer Adventures, based on the 1980's British science fiction Comic Book. The Demoralizing Stance stunt allowed you to intimidate opponents by demonstrating your fighting techniques.

Video Games

 * In the Metal Gear Solid games, triple-crossing Magnificent Bastard Revolver Ocelot is rarely seen not elaborately twirling around his revolvers to intimidate his foes and his allies. It's played for both silliness and creating menacing tension.
 * Parodied in the Gold/Silver era Pokémon games. One gym leader tries to intimidate you when you challenge them by throwing and smashing a rock, only for the Player Character (based on what said gym leader says) to point out that has nothing to do with how good he is at Pokemon battles.
 * In Soul Calibur, each character is focused on for a few seconds before a round starts. While many characters simply taunt or toss their hair, some, such as Taki, Kilik, Hwang and Maxi will use that brief moment to take out their weapon and twirl it about while letting out a Kiai.
 * A rare instance where this trope is used to end a fight rather than start one. In Blaz Blue: Continuum Shift, Carl Clover interrogates Tsubaki Yayoi a little too roughly, and Makoto, not knowing who the aggressor is but wanting to stop the abuse, jumps out and prepares to punch him. Carl dodges - and good thing, too, as the punch leaves a massive impact crater where he once stood! Unfortunately for Makoto, this causes Carl's attention to shift to her, as she's with Intel and Carl wanted the whereabouts of his father, Relius Clover...

Web Animation

Western Animation

 * In the Daffy Duck short Muscle Tussle, Daffy's girlfriend is wooed by a beach hunk. Daffy takes some strength tonic in order to match up with the new guy. The new guy demonstrates his strength to Daffy; Daffy tries to match him but the results are less than stellar.
 * Popeye: Popeye has various ways he shows off just how strong he is; virtually every time he eats spinach, he flexes his now-humongous biceps.

Real Life

 * Very common in animals, especially mammals, but sometimes birds as well. Males will face off against rival males to prove strength and fitness for the right to mate. Deer, antelopes, buffalo, elephants, humpback whales(rare nonphysical singing contest version), rams, lions, horses and others all do it. And yes, it can go to the death for some species.
 * There's also the mating variation, where the male tries his best to impress prospective mates with strength, various skills, displays, ect.
 * Also a frequent defense mechanism. Prey animals will try to ward off an enemy by showing they are too strong to target. Good example is the 'pronking' behavior of some antelope species.
 * In Ethology this is called a "threat display".
 * Wargame Designer James Dunnigan commented that this was one of the reasons for Bling of War: it costs a lot less to look Badass then to be badass. And hopefully everyone else will either believe you or know their own troops are just as incompetent.
