Rule One 

The Doctor lies. (from Doctor Who)

Amy: But he (the Doctor) was dead.
River: Who told you that?
Amy: He did.
River: Rule one: the Doctor lies.

River: He said no one could save him. But he must have known I could.
The Doctor: Rule one: the Doctor lies.

River: Okay. I'm going to tell you what I probably shouldn't. The Doctor's last secret. Don't you want to know what he whispered in my ear?
Amy: He whispered his name.
River: Not his name, no.
Amy: Yeah it was. He said it was.
River: Rule one?
Amy: The Doctor lies.

Rule One 

The Doctor lies.

Most of River Song's "The Doctor lies" is about it being her own rule #1 for figuring out what's going on when things don't seem to make sense. If things seem incomplete or impossible, consider first if The Doctor lied about something.

Rory Williams: Why did he tell us he was dead?
River Song: Rule One: The Doctor lies. So do I.

Rule One 

Literal translation is 'don't be a pussy'. Most often used when berating someone with 'you forgot rule one' implying that if one has forgotten rule one then they're indeed a pussy.

Dan: I'm a little tired, my boots are chaffing and the wind is blowing in the wrong direction.
Gora: You're in violation of rule one. Get over that kicker.

Rule one 

Rule one refers to the first rule of deciding if someone is worth getting involved with: "Never put your dick in crazy". Other more gender-neutral ways of phrasing this rule such as "never invest in crazy" have been suggested, but the central meaning stays true regardless of phrasing.

A:"Oh man, do you think I should get with him?"

B:"No, chicka, he breaks rule one."

A: "Okay, not happening then."
