look up any word, like fleek:
 
1.
Binary is a base-2 number system made up of only two digits 1's and 0's.

The term BINARY RULE refers to the common phenomenon where a couple will usually be made up of a large or fat person aka a ZERO and a slim one aka a ONE. So if you want a skinny partner you better put some weight on!

This term is being used regularly on the streets of Birmingham, UK where it was discovered.
Some examples and proof of the Binary Rule would be; Fred Flintstone is a binary 0 and his wife Wilma is a binary 1.

Or any bodybuilder would be a binary 0 and his petite skinny bimbo would be the binary 1.
