|1.||reverse Oedipus complex|
The origin of gay men according to Freud - it works like the Oedipus complex but the other way around, i.e. little boys want to fuck daddy and kill mummy. Supposedly arises in all little boys, and develops into homosexuality when it's stronger than its hetero inverse.
Peter Mandelson probably had a reverse Oedipus complex as a kid.
