"to carry or drag," 1922 (in Joyce's "Ulysses"), from Yiddish shlepen "to drag," from Middle High German sleppen, related to Old High German sleifen "to drag," and slifan "to slide, slip" (cognate with Middle English slippen; see slip, v.). Related: Schlepped; schlepping.

"stupid person, loser," 1939, short for schlepper "person of little worth" (1934), in Yiddish, "fool, beggar, scrounger," from schlep, v. "to carry or drag" (for sense evolution, compare drag, n. "annoying dull person").
