Narcissists thrive on control and having the upper hand in every conversation, so when someone pushes back or challenges their inflated ego, it doesn’t sit well with them. These are the 10 phrases that can catch them completely off guard, and more often than not, they’ll respond with anger.
“That’s not about you.”

Few things throw a narcissist off like being reminded that not everything revolves around them, because they’re used to inserting themselves into every situation. Hearing “that’s not about you” can therefore feel like a slap to the ego, where it cuts through their need to be the center of attention and challenges the idea that their perspective is always the most important.
“I don’t need your approval.”

Validation is a major tool narcissistic people use to control others when – if you rely on their praise – they hold the power. However, when you calmly express that you’re confident without their approval, it undercuts that control completely, telling them they can’t manipulate you through compliments.
“Let’s agree to disagree.”

They see disagreement as a difference in opinion and as a personal attack on their authority or intelligence, because when someone refuses to engage in a power struggle, it’s infuriating to them.
It furthermore signals that you’re not going to be baited into proving them wrong, and that you don’t see their opinion as absolute truth – and that’s a hard pill to swallow.
“You’re not the victim here.”

Turning the tables on a narcissist’s favorite tactic (playing the victim) can stop them in their tracks; they often twist situations to make themselves look like the ones who were wronged, after all. Therefore when you call this out directly, it forces them to face something they’re rarely held accountable for, and don’t be surprised if they lash out.
“No.”

A simple, firm “no” can be one of the most powerful things you say to someone with narcissistic personality disorder, and it’s also one of the most upsetting for them to hear. They’re used to people giving in or bending over backward to keep the peace, and when someone sets a boundary without explanation or guilt, it threatens their sense of control.
“I’m not going to argue about this.”

Drag people into endless arguments to wear them down, confuse them, or just feel like they’re winning is something they love to do, which is when you opt out of the fight altogether, it throws them off balance.
You’re taking away their favorite playground – saying this shows you’re not emotionally invested in feeding their drama, and it also communicates that your peace of mind matters more than being right.
“That’s your opinion.”

To a narcissist, their opinions are facts and for this reason, they expect everyone to agree or at least acknowledge their brilliance. When you respond with, “that’s your opinion,” it strips their words of power and frames their viewpoint as just one of many, reminding them that others don’t have to agree.
“That’s not acceptable behavior.”

Especially in a direct, calm way, calling out this kind of person’s bad behavior can hit them harder than yelling ever would, putting a mirror up to their actions. As a result, you aren’t allowing space for excuses or manipulation, which is what they usually rely on, so being told flat out that something they did isn’t okay threatens their carefully controlled image.
“I don’t play mind games.”

Letting someone with narcissism know you’re onto them and not willing to engage in manipulation takes away their upper hand; this could be guilt-tripping or emotional baiting, the kind of mind games that give them control. Refusing to participate in that kind of behavior sets a boundary they weren’t expecting, and usually don’t respect.
“I’m focusing on myself.”

What’s one of the biggest things a narcissist wants the other person to do? Focus on them, therefore nothing is more frustrating than someone who’s no longer doing that, and is instead prioritizing their own growth, health, or happiness, sending the message that you’re pulling your energy away from feeding their ego.
