Here is what students in Biology 221a at UWO get: 
 
Parasitism is a relationship between two organisms, the larger of which   
is physiologically dependent on the smaller; where the incidence and   
prevalence of parasites in the host population is non-random; where the   
reproductive potential is higher in the parasite; and where the parasite   
has the potential to cause harm to the host. 
 
I ripped this off from somewhere, can't remember where, but it is the   
basis for an entire lecture on each aspect of the definition.  The last   
part of the definition may be relevant to previous discussion in this   
list.
