The act of repeatedly stopping by a co-worker's cubicle trying to ask them out on a date by feeding them a lame come-on line. It usually involves the person doing the macking actually leaning on the outside of the mack-ee's cubicle unit so as to make for a more intimate setting, while keeping respect to "boundaries," to ask a non-work-related question rather than coming around to the inside of the person's cubicle to discuss a legitimate, work-related topic.
Alfonso keeps cube macking on Sally to see if she'll go on a date with him; even though he's cube macked on every single woman in the office and they've all said no.
