How would you handle this?

As some of you know I started a new job last week and I work in a corporate environment. Thursday afternoon as I'm walking to my office, I pass the elevator and a guy steps out. As he passes me he says "What's up juice bag."

I was in shock. I stood there, and the only thing that could come out of my mouth is "That was really f ucking nice. I can't believe you just said that." By then he turned the corner and was gone. I kept walking and went back to my office and debated whether to go to his office and say something to him about it. I decided not to. I thought my comment would give him a clue what he said was inappropriate.

Friday morning my manager called me to his office for a meeting. As I'm about to walk in, I look up and I see the guy. He says to me "Good morning juicey" I said back What did you just say? He repeats it. "Good morning juicey." I said back to him VERY SERIOUSLY "Do not EVER... say something like that to me again." and then walked into my manager's office. When I sat down my manager asked me what did he just say to you. I told him nothing. He asked me again 3 times what did he say. I told him nothing, do not worry about it. I'll handle it.

Friday afternoon as I was getting lunch in the cafeteria I see the same guy sitting at a table with some other guys. As I'm stacking a load of food on my tray. One of the guys with him walks up to me, thinks he's being funny and says. "So, how much do steroids go for these days." I said back, "I don't know. But if you say something like that to me again I will report you to HR."

What do you guys think? Monday should I talk to my manager about this? Should I go to HR? I feel by reporting it to my manager and HR it's going to put a spotlight on me and on the subject of me using steroids. I just started this job and I feel being new, I shouldn't make waves but these f uckers are disrespecting me with their comments and I don't like it.
