A malt liquor is any alcoholic beverage containing a portion of fermented malted barley. All beers are malt liquors.

Brew Your Own has a recipe for malt liquor on there site (http://byo.com/recipe/1453.html). According to this recipe, to make an American Pilsner you dilute five gallons of malt liquor with one gallon distilled water. Perhaps malt liquor is the base to American pilsners, who knows if this is the way they do it at the brewery.
FYI... I had some Weihenstephaner hefeweizen that was labeled "Malt Liquor" a while ago.
