Different from the classic 1 to 10 scale of rating women, or the ever popular 1 to 3 scale, the binary system is a simple choice of yes or no.
The Binary System is best used when one is on a dry streak and looking to get drunk and get laid... not necessarily in that order.
There are only two choices in the binary scale: 1. Yes, I'll fuck her, or 2. No, keep that skank
"Dude, I am pretty fucked up, so I am switching to the Binary Scale of Hotness"
"Alright man, go get your dick wet!"
