look up any word, like swag:
another term used to describe the scale by which hot women are measured. The scale ranges from 1 to 10 and women are given higher numbers depending on thier ability to induce an erectile response in males merely by being in the room.
Bro 1: "dude check out that chick, she scores at least a nine on the erector scale!"

Bro 2: "Gross dude, she's barely a five."
