1) Like "Oedipus Complex", except for less creepy and far sexier
2) Being severely sexually attracted to your
girlfriend's or wife's mother, as described in the Fountains of
Wayne hit "Stacy's Mom."
3) Willingness to leave your significant other for his/her mother.
Guy One- "Dude, the only woman
I would leave my
girlfriend for is her mom. Have you seen her?!?!?"
Guy
Two- "Yeah man, your Stacy's Mom Complex is completely justified"
