Guys, do you outgrow being mean to girls even as an adult?

I have this male co worker who likes to get in my face every single day just because and I never ever give him the reaction he wants. He likes to mind my business all the time, like what is up with him! He’s not my boss, nor a manager. But he’s always trying to get my attention. I ignore him or pretend I didn’t hear or see him. Coz he’s irritating the hell out of me. And imma about to report him! What should I do? I’m only 3 months on this job but I really like this job. I don’t want problems and he seems like the manager’s pet too.
