What is scum bag?

Famous quotes containing the words scum and/or bag:

    The people of this country are too tolerant. There’s no other country in the world where they’d allow it... After all we built up this country and then we allow a lot of foreigners, the scum of Europe, the offscourings of Polish ghettos to come and run it for us.
    John Dos Passos (1896–1970)

    Name me, if you can, a better feeling than the one you get when you’ve half a bottle of Chivas in the bag with a gram of coke up your nose and a teenage lovely pulling off her tube top in the next seat over while you’re doing a hundred miles an hour in a suburban side street.
    —P.J. (Patrick Jake)
