Trimmed NURBS are, to my understanding, a NURBS surface with geometry holes
or subtractions in it.  For example, a screw head is domed, but has slots
cut in it for the screwdriver - if there were no slots, it would be a
regular NURBS surface, but cutting slots creates a trimmed NURBS surface. 
Likewise, a flat NURBS surface with a hole punched into the center is a
trimmed NURBS surface.
