DAU /dow/ [German FidoNet] n.

German acronym for Dümmster Anzunehmender User (stupidest imaginable user). From the engineering-slang GAU for Grösster Anzunehmender Unfall, worst assumable accident, esp. of a LNG tank farm plant or something with similarly disastrous consequences. In popular German, GAU is used only to refer to worst-case nuclear acidents such as a core meltdown. See cretin, fool, loser and weasel.
