Bag Scale

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.
