Coitus Mysterioso 

Drunken sexual encounter where coitus may or may not have occurred.

Charlie thinks he had sex with this girl a few weeks ago, and she was begging for it, but he's never had sex with her before, or after, so for now it's classified as a case of coitus mysterioso.

the mysteriously vanishing 40-year old actress

The worst kept secret in American entertainment - be it film, stage or television : be a woman, be an actor and turn 40 years old, and your career is effectively over. You're done.

The American actress Hilary Swank a few years back played the lead in a film called 'Amelia', a biopic about Amelia Earhart. Earhart, for those of you who may not recall, was a famous early 20th century American female aviator who, at the age of 40, mysteriously disappeared and was never seen again. Ever. Which, when you think about it, is right up Hollywood's alley because if you're an actress and you're in Tinseltown and you turn 40, you disappear, too. Never seen again. Never. Ever. The mysteriously vanishing 40-year old actress.
