Creepy guy at work what do I do?

I am from Bulgaria and moved to the states. I work in the bakery at a grocery store and at a seafood buffet at nights. Their is this guy about my same age and he constantly stare at me. I guess american women find him to be attractive. He is very muscular tan and clean cut but that is not what bulgarian women like. He tried to talk to me outside on my break and ask me what my name was and I showed him my nametag and he scoffed at me and walk away. He started a rumor that I was a stuck up ***** and now nobody at my job wants to talk to me. I dont know what to do because he is one of the main managers and everybody adore him where I work but he gives me dirty looks. I went in office to ask for my check and he walked out and said somebody else would give it to me and brought a older lady to come in and give me my check. What do I do?
