Wondering what a nickname for someone who thinks they know everything is?
The most common nickname is a know-it-all, which literally means they think they know it all (everything).
Of course, you can come up with your own nicknames if you know someone who acts like this and there are some other words you can use!
Nickname for Someone Who Thinks They Know Everything
The most common nickname or word for someone who thinks they know everything and acts all high and mighty is a know-it-all.
A know-it-all is defined as a person who acts like they know everything and are never wrong.
They also have a superiority complex, thinking they are better or smarter than others.
If you know someone like this, I don’t need to tell you how frustrating it is dealing with them!
You can use this nickname for them in the future, and the penny might drop for them and they’ll realize how they’re coming across!
Or not, as the case may be for most know-it-alls!
What Is a Superiority Complex?
A superiority complex is when someone thinks they are better, smarter, or more important than others.
It can manifest in different ways, such as thinking you are more attractive than others or being arrogant.
A superiority complex can make someone difficult to be around as they think they are always right.
If you know someone with a superiority complex, you might find yourself getting annoyed with them frequently!
It’s important to know, however, that you can’t change them by simply telling them to stop showing off or pointing out how they’re behaving.
The reasons for their behaviors run a lot deeper than that and only they can work on themselves to change.
How to Deal with A Know-It-All?
The best way to deal with a know-it-all is usually to just walk away or keep your distance.
There’s no point in engaging with them or trying to prove them wrong as it’s likely a fruitless endeavor.
Arguing with a know-it-all will only make you more frustrated, no matter what angle you approach an argument from and what evidence you have, they’ll find a way to twist it to suit their own answer.
If you can’t avoid them, try to keep your conversations surface-level and be prepared for them to try and one-up you or act like they know more than you.
At the end of the day, you don’t need to prove anything to a know-it-all, so don’t let them get to you!
What Do You Call a Person Who Thinks They Are Always Right?
There are a few different words or phrases you could use for someone who thinks they are always right.
A know-it-all is the main one I’ve covered so far, but some other words you could use to describe them are:
Egotist – This means someone who is obsessed with themselves and their own importance.
Narcissist – A narcissist is someone who has an inflated sense of self-importance and a strong need for admiration.
Elitist – An elitist is someone who believes they are better or more qualified than others.
Arrogant – An arrogant person is someone who is excessively proud and behaves in an overbearing or disdainful way.
Swellhead – A swellhead is someone who is conceited or thinks too highly of themselves.
If you prefer one of these words over a know-it-all, go ahead and use it as a nickname for anyone who seems to think they’re always right and know everything!
What to Do if You’re the Know-It-All?
If you’re reading this and thinking to yourself, “Wait a minute, I think I’m the know-it-all!”
Don’t worry, you’re not alone.
It’s easy to fall into the trap of thinking you have a good answer to everything, especially if you’re smart and confident.
I’m sure you’re only trying to be helpful and you have other people’s best interests at heart, but there is a lot to be gained from taking a step back before talking.
Try and listen more than you talk, even if it feels like you have the perfect solution to whatever problem is being discussed.
Also, try and offer advice based on experience and proof if possible, rather than going off of what you think or feel.
If you can do these things, people will be a lot more likely to listen to you and appreciate your input!
Being called a know-it-all isn’t the worst thing, but it’s something to take notice of and make some changes!
