The "blurness" of the background is dependent on the subject distance, the background distance and aperture size. The closer your subject is relative to the background and the larger your aperture (note: larger aperture = smaller f number) is, the more blur ur background will be.
| = background
x = subject
c = camera
|_____x________c = less blur
|_________x____c = more blur
Also, try opening your aperture to the max (smallest f number) that your lens can support (for 18-55 kit lens, that would be f/3.5 at the 18mm end and f/5.6 at the 55mm end).
Lastly, the kit lens unfortunately is unable to "blur" off much of the background (given the relatively small aperture compared to, say, a f/2 lens). Your best bet would be to keep ur subject as close to you as possible with a far off background. If that cannot be done, you will need a faster (smaller f number) lens, such as the cheap and excellent 50mm f/1.8.
Bokeh is a qualitative term to describe the blurring / oof, and it is can good or bad. From the starting thread do not think bugsz is talking about the quality of the blur here, but rather have more or less of the oof areas.
