"Leck mich im Arsch" is a song by Insane Clown Posse and Jack White.
The lyrics are inspired by Leck mich im Arsch, a scatological canon by Wolfgang Amadeus Mozart (K. 231/382c), while the music is based on a canon called Leck mir den Arsch fein recht schön sauber (K. 233/382d).
[1][2] White played the track he was working on, an arrangement of Wolfgang Amadeus Mozart's "Leck mich im Arsch" with live instrumentation by JEFF the Brotherhood, for Bruce and Utsler and explained that the title of the track translated to "Lick My Ass".
[2] Insane Clown Posse said that the song was a collaboration and that White asked them for their feedback throughout the recording process.
The song was released as a single on September 13, 2011 by White's label Third Man Records.
