If a guy is lingering around your table but won't say anything to you is he waiting for you to talk to him, is there a meaning to what he is doing?

I Don't know him, I just seen him for the first time at my school food area and I kept eyeing on him because I had found him attractive. Then all of the sudden I started to see him more frequently. And I know he knows I find him attractive because I once seen him have a smirk on his face while looking straight ahead while I was like 8 feet from him looking at him. While I was with my friend, he got up twice and passed by my table with both hands in his pockets and one time was to throw something out at a garbage by my table and since that was the second time he passed by my table, I felt like he did all of that on purpose.
