An Etymological Dictionary of the German Language/Annotated/schlemmen

by Friedrich Kluge

schlemmen, ‘to carouse,’ from late Middle High German slęmmen, ‘to squander,’ allied to late Middle High German slamp, ‘carouse’; compare Dutch slemp, ‘dainty meal,’ slempen, ‘to carouse,’ with which Schlempe, feminine, ‘rinsings,’ is connected. The term is wanting in the other Teutonic languages.
