Difference between looking and staring?

Anonymous
Just curious what the difference between looks and stares from guys are. Guys seem to look at me when passing by, only for a few seconds but I've heard it only means something if a guy stares for a long time, not just a quick second glance. So what is the difference between them? Does just a few second look mean anything? Thank you :)
