Will guys purposely try to bump into you?

A couple months ago this guy was flirting with me and calling me beautiful asking if I had a boyfriend (which I did but not anymore). So he stopped flirting with me but it seems like he's at it again (for all he knows I may still have a bf). Last week he told my again how pretty he thought I was and then at the end of class I was walking to the door and there's no way he didn't see me but he almost walk right into me (face-to-face) and the way he did it I can tell it was purposely. What is the satisfaction a guy would get from doing this? Lol
