Trinary Scale

Evolving from the binary scale for rating females, the trinary scale attempts to incorporate the influence of alcohol on the binary scale. For example, instead of the usual 0 = won't bang and 1 = will bang, the trinary scale goes from 0 to 2, where 0 = never bang, 1 = will bang drunk, and 2 = will bang anytime

Jack: Dude, I saw this girl in class who was a legit 2 on the trinary scale
Sam: Whatever dude all you bang are 0's anyway
