"Parasitically" describes a relationship where one organism (the parasite) benefits at the expense of another (the host). It implies a dependence that is harmful or exploitative. Think of it as someone leeching off another person's resources or efforts without contributing fairly. It emphasizes the unequal and often damaging nature of the relationship. It can be used metaphorically to describe social or economic situations. It's like a freeloader on a grand scale.
