Hey I was just using the name of a very famous painting that is much discussed throughout Duchamp literature and any library should have much more additional information on it.
The PC title for the work is Tu m. Theoretically, "Tu m'" could be followed by any verb starting with a vowel, but the most
common usage back then was 'tu m'emmerdes' (See: Arturo Schwarz, Completed Works by Marcel Duchamp, vol. II, New York: Delano, 1997, cat. no. 354, p.658).
The piece itself was commissioned by
Katherine S. Dreier for a space above her
bookshelves. Although 'Tu m'" could stand for
'Tu m'aimes', 'agacer, ennuyer, emmerdes'
(irritate, annoy, bore stiff) is more likely,
reflecting either on the old and
'dead' process of oil painting or on Duchamp's
sometimes troubled relationship with Ms. Dreier
(cf: Dawn Ades (ed.)Marcel Duchamp, London:
Thames and Hudson, 1999, p. 172-73).
