: Something that sends a character into a violent rage.
- Straight: Brad, normally a rational and non-aggressive person, beats the crap out of someone because they insulted his mother.
- Someone touches Brad's shoes. Brad, normally an Extreme Doormat, goes on a murderously psychotic rampage that results in the deaths of the people responsible.
- Brad has a Hair-Trigger Temper, or put another way, he has quite a few Berserk Buttons and people press them frequently.
- Downplayed: Brad is normally the Only Sane Man, but he'll go into a long and brutal rant if someone calls him a bastard.
- Brad's mother was a prostitute, and it's a sore spot for him. Besides, Even Bad Men Love Their Mamas.
- Brad is a literal bastard, which is why he takes such offence to that particular insult.
- Brad has a bad childhood memory of the incident.
- Brad being called a bastard causes him to mope.
- Alternatively Brad is The Berserker when he's not baking, referring to pastries really mellows him out.
- Brad usually has Hair-Trigger Temper when it comes someone talking to him unless someone calls him imbecile at which point he doesn't care.
- Kindness Button
- Subverted: Brad looks like he's going to snap, but he doesn't...
- Double Subverted:
- ...but then some more jeering sends him down the deep end completely.
- Or it just looks like he didn't snap, because he went into Tranquil Fury.
- Brad's occasionally driven to violence, even to the point of challenging someone to a chicken race once, whenever someone messes with his shoes.
- Brad is a robot with a button labeled "Berserk" on his back. Pressing it will make him angry.
- Zig Zagged: After being pushed too far, Brad picks a fight with the scoundrel but is horribly outmatched. Now his face makes his shoes look intact by comparison.
- Averted: The things that would be Brad's berserk buttons don't bother him at all.
- Enforced: The writers want to show that even nice guys can break.
- Lampshaded: "Don't do that. He'll break your neck if you do."
- Invoked: "I heard that he's sensitive about his shoes. Let's spill mustard on them and see what happens!"
- Jack, the hero, uses Bob's Berserk Button to take down the Dark Lord.
- A villain uses Bob's Berserk Button to get him in serious trouble with the authorities or get him killed.
- Defied: "You think that's going to piss me off?! Ha! You're wrong!"
- Discussed: "Just...don't mention that one thing around him. Trust me on this one, okay?"
- Conversed: "Oooh, that character is being set up as an idiot." "How do you know?" "He just called Brad a bastard... a second time."
- Deconstructed: Brad's reaction to his Berserk Buttons get him into deep trouble with horrifying consequences for all.
- Reconstructed: ... but he has made sure NO ONE will ever make fun of his shoes again
- Played For Laughs: Bob's Berserk Button itself and/or his reaction when it gets pressed is utterly ridiculous.
- Played For Drama: Bob's Berserk Button leads to someone getting hurt or even killed, leading to everything going to hell for him.
