inframince
n.— «The back cover, a message built of collaged letters, demonstrates Duchamp’s notion of “inframince,” a neologism of his that, he stated, could not be defined, only illustrated: “When the tobacco smoke smells also of the mouth which exhales it, the 2 odors marry by the infra thin [sic].”» —by Maria Fusco Frieze Apr. 13, 2006.
