Man on the Moon 

When having sex with a chick and you are doing her from behind, right before you "finish", you take a flag with your name on it and stick it into her ass hole and as you finish you yell out "I'm the man on the moon!".

Guy1: "Last night I conquered new territory, I took that fine ass home and planted my flag!"
Guy2: "Dayam man! You pulled a man on the moon on her ass!"

Goodnight Moon 

Arguably the worst children's book ever written.
Especially because it implies something else. Something not meant for children.

"I bought 'Goodnight Moon'. Obviously, it was not the type of moon I hoped for.

Suck your dad's dick on the Moon 

To care so little about someone's opinion that you are willing to expend an extreme amount of effort to show how little their opinion matters to you

"You think I give a shit what he thinks? I'll suck your dad's dick on the Moon!"

"As if it weren't clear enough how little James thought of his critics, he proceeded to suck their dad's dicks on the Moon."
