In short, some characters almost always get enraged when given a certain trigger.

Say you're dealing with a character who seems perfectly normal. They're a [[NiceGuy nice person]]; friendly, sociable, and well-adjusted, saving stray kittens and helping old ladies cross the street on the way to their day job of working at a soup kitchen.

[[BewareTheNiceOnes But then you make a mistake]]. You happen to mention in passing what you think is a fairly innocuous observation, maybe pointing out that they could stand to lose a little weight, or is [[HeightAngst a little on the short side]], or maybe could use a girlfriend or boyfriend, or you do something that you think is no big deal in their presence, like question WhoNamesTheirKidDude. And the character instantly goes ''ballistic'', flying into a screaming, frothing, sometimes [[BerserkerTears tearful]] UnstoppableRage, from which you will be lucky to escape with your life.

You have just pressed the Berserk Button.

The Berserk Button is one type of UsefulNotes/{{Trigger}}, where the response is one of extreme anger. That is, engaging the trigger turns an ordinary character into TheBerserker.

In comedic works, the Berserk Button tends to be a physical feature that the character is insecure or in denial about, like their {{height|Angst}}. Animals also don't seem to like having their [[IAmNotWeasel species misidentified]]. Comedic Berserk Buttons are often used to make an otherwise unflappable character lose their cool and go off on a hilarious rant. In cartoons, you can usually tell when a Berserk Button has been hit when the character who has it turns bright red and [[BurningWithAnger steam starts shooting out their ears]].

If a person seems to get angry over anything and everything, they have a HairTriggerTemper. For the negative effects of hitting the Berserk Button, see YouWouldntLikeMeWhenImAngry. For the trope's opposite, see KindnessButton. See also TraumaButton. Compare and contrast RantInducingSlight and RageBreakingPoint, where it's a series of events that causes them to no longer be able to hold back anymore. If a person gets angry that other people aren't taking a (very unimportant) thing seriously, see SeriousBusiness.

'''This trope is not about anger in response to something that would reasonably enrage someone, like being hurt or threatened, having a loved one hurt or threatened, being seriously insulted and disrespected, etc -- anger in those situations is a reasonable response. ([[DisproportionateRetribution Extreme reactions to minor provocations]] may still qualify, however.) Also, Berserk Button does not apply if the worst that happens is if the character scowls or frowns at the provocation. It's "''Berserk'' Button", not "Mildly Put Out Button".''' If you see such an example on the page, or were link here by such an example, '''please remove it'''.

* Literature/TheFourGospels see [[UsefulNotes/{{Jesus}} Christ]] advocate for love for enemies repeatedly, but Christ's love can be tough, as seen when he finds Pharisees making a marketplace out of God's temple. Christ is furious at the worship of money, the selfishness of the Pharisses, and most of all, their hypocrisy for doing this while claiming the moral high ground. The messiah proceeds to flips the tables in the Temple and chases the Pharisees from the Temple.
