There is one annoying junior colleague in the office. We are in the same project but on different teams.

For reasons best known to him, he has made a nasty comment about my experience in the industry. He also hijacks my conversations with other colleagues and keeps staring at me whenever I pass by their bay.

I'll be meeting my boss soon. She usually works from remote location and will be soon visiting the office.

I am not sure about my boss's nature. My main intention is to let her know about his nasty behaviour.

I was wondering if I can mention about this junior to her?

Before escalating to your boss, you should try to resolve whatever issue you have with your colleague first. When they make any nasty comment about yourself or your experience you need to respond immediately with something like:

Hey X, that comment was nasty and uncalled for. Please refrain from making such comments about myself.

When he attempts to hijack your conversations you can say something like:

Excuse me X, I am discussing Y with Z at the moment. If you need to speak with either of us you can do so after we have finished our conversation.

If after directly confronting this colleague they continue to behave rudely, you can then speak with your boss about it. Try to document as much as possible and if any of this rudeness is done electronically save that evidence.

TLDR: Your manager should not be bothered with this.

What you are describing is, at most, rude behavior. If I were in the position of your manager, I would be less than sympathetic.

My first question to you would be:

Have you spoken to him about it?

The next would be

What steps have you taken to resolve this conflict?

You need to deal with this, or at least attempt to, on a person to person manner. If you take this to management before having exhausted other methods, it could reflect poorly on you.

Going to your manager now could make you look weak and incompetent, there's a great difference with going to your manager with what you have now.

For reasons best known to him, he made a nasty comment about my experience in the industry. He also hijacks my conversations with other colleagues, keeps staring at me whenever I pass by their bay.

and something like.

Tom has been commenting on my experience, and has been disrupting my conversations. I have spoken to him about his conduct on The fifth, again on the twelfth and again on the 18th, and his behavior hasn't changed. Do you have any ideas how I should deal with him, or do you feel you need to get involved at this point?

Before you approach your manager, make sure you've taken steps to address the problem and resolve it. Do not use management as a means to take revenge on someone's rude behavior, or it could backfire terribly.

If this person seems to have a particular dislike for you and not others, it would probably be best to have a quick chat with them before speaking with your boss. Do this in private.

Give them an opportunity to air any grievances; It's possible you may have done something to upset them.

Once they are finished, explain that there are behaviours that you find offensive and that you want them to change.

Once the discussion is over, immediately make a note of the contents of the discussion.

Even if the meeting doesn't seem to go well, give them an opportunity to change their behaviour. Some people don't react well when confronted, but on reflection realise they are in the wrong.

Don't expect drastic change immediately. If they continue their behaviour, small cues like a raised eyebrow, a frown, or a tilt of the head can remind them of your discussion.

If you don't see improvement, yes, you can raise this with your boss. You can do this at any stage, you do not have to wait for your boss to be in the office.
