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!"

5 x 5

If you are "all square" with someone (as opposed to being just a square), or you are cool with that person, then you are 5 x 5.

We talked through our differences, so now we are 5 x 5.

5 Session Rule

A common knowledge webcam rule stating that it's okay for straight guys to jerk off with each other on cam as long as it doesn't exceed 5 sessions. If it exceeds 5 sessions, then they are gay. Derived from the "5 second rule".
