While a one night stand makes her feel used, a second hookup validates her worth. Then bail.

A sith law making it so that there can never be more than two active sith at one time, one master, and one pupil. The rule was set in place by Darth Bane after he killed all the other sith.(Darth bane also started the tradition of prefixing sith names with "darth")
Darth Sideous only ever had one deciple at a time, first Darth Maul, then Darth Tyranus, then Darth Vader. Although he surounded himself with other Dark Jedi, there were only ever two Sith at one time, in accordance with the Rule Of Two.

As stated in Alice's Adventures in Wonderland: "All persons more than a mile high, to leave the court."
Quote:

At this moment the King, who had been for some time busily writing in his note-book, cackled out 'Silence!' and read out from his book, 'Rule Forty-two. ALL PERSONS MORE THAN A MILE HIGH TO LEAVE THE COURT.'

Everybody looked at Alice.

'I'M not a mile high,' said Alice.

'You are,' said the King.

'Nearly two miles high,' added the Queen.

'Well, I shan't go, at any rate,' said Alice: 'besides, that's not a regular rule: you invented it just now.'

'It's the oldest rule in the book,' said the King.

'Then it ought to be Number One,' said Alice.

All persons over a mile high should not be in court. It is the oldest rule in the book.

This term is a universal rule of probability. The rule states that whenever there is a picture on a dating app that contains two girls, with one of them being significantly more attractive than the other, the person whose profile you're swiping is the less attractive of the two.
When I saw Isabella pictures on Tinder I got excited when I thought she was the hot girl on the right....turns out I fell victim to the Tinder Rule of Two.
