A person who is a self-proclaimed fan of the Jenny/Niki pairing from Showtime's series The L Word that features central character Jennifer Schecter hooking up with a 21-year-old ditzy
bimbo of an actress named Niki Stevens who behaves as though she's 10. The Jenkis are the
people who coined the term Shencest as a response to the
people who wished to have Jenny and her
long-time
friend Shane McCutcheon become a couple, saying that the two are like sisters. The Jenkiphile term was created in response - because if the Shenny are into
incest, the Jenkis are into pedophilia, considering Niki's diminished mental capacity and extreme emotional immaturity.
Jen(ny) + (Ni)ki + (pedo)phile = Jenkiphile.
Typically, fans of this pairing are shallow, ignorant teenagers who are only into the relationship because Niki is aesthetically attractive and because she and Jenny are supposedly cute together.
