A combination of the Oediups and Electra complexes.
In the Oedipus complex, a man has sexual feelings for his mother, and the desire to dominate or kill his father.
In the Electra complex, a woman feels castrated by her mother, and resents her, and has sexual feelings for her father.
In the Electrapus complex, the woman has sexual feelings for her mother, and a dislike of her father.
These complexes are not to be taken literally. Not all men with an Oedipus complex actually have sexual feelings for their mother- most just end feeling desire for a woman that greatly resembles their mother, either in appearance, in personality, or both. Likewise with the Electra complex, and the Electrapus complex.

Girl 2: You've totally got an Electrapus complex, chickie.
