When you see someone mention backfocus, it's when what you're focusing on (selected focus point) is out of focus, and what's in back of it is in focus, hence the term backfocus.

In other words, the camera is focusing behind your intended subject.

This is more noticeable when you're "filling the frame" with a smaller subject (by using a closer focus distance or longer focal length),using larger apertures (smaller f/stop numbers), where Depth of Field is shallower.
