A polite way of saying "motherfucking asshole," as Oedipal refers to the "Oedipal Complex," in which a boy/man has feeling of romantic and/or sexual love for his mother. Oedipal, in turn, comes from "Oedipus," the character in the play by Sophocles, who grows up away from his mother and later marries her without knowing who she is and his relation to her.
Anus, of course, is that posterior anatomical orifice also known as the "asshole."
