"Jeff" is a reference to a stereotypical character found in a movie or T.V. show written with exaggerated and unrealistic misogyny. This is done in order to showcase a female protagonist, usually a superhero or some other role that might be more male dominated. They often are a writing crutch, replacing depth for the female character with a quick obvious stand-in of generic male villainy, and a stage for the protagonists "Girl Power".
Named from the character "Jeff", in the 1970s "Spiderwoman" cartoon, who was buffoonishly stupid and sexist about Spiderwoman's capabilities.
The criticism inherent in the term is that a well written female doesn't need a comically evil male to make her look good.
