Like the normal scale used to rate chicks 1-10, but rated as if there was a paper bag on their head.
"Check out that chick with the busted face!"

"Whatever that shits like a paper bag 7."

(aka 7 out of 10 on the paper bag scale)

Get the Paper Bag Scale mug.
Scale having a range from zero to three describing the sexual attractiveness versus the ugliness of the intended partner. Compiled from Bag Job (=1 or single bagger), Double Bagger (=2 or an insurance bag on one's own head in case the partner's bag should fall off or rip) and Triple Bagger (=3, indicating that the dog should also have a bag placed over it's head otherwise the carpet may become covered in dog faeces and vomit when the poor mutt witnesses the horrible act).
Sweet Jesus! She was so ugly I would have to give her a 2.8 on the Bag Scale.
