What is 5-point Scale?
A scale for rating the attractiveness of a girl (usually). As suggested by its name, it consists of a scale 1-5, with the highest rating being the rare 5.0. As a rule of thumb, the threshold of dateability lies at the rating of 3.0.
In addition, a maximum of 0.5 points may be added or subtracted accordingly, based on the subject's personality. No rating is to exceed 5.0.
"Without personality, I'd probly give that girl a 2.0 on the 5-point scale...I'd LET her suck my dick..."
"Dude, that girl's an asshole, but she's def. a 4.2!"
