The lutz jump was invented by a Austrian man named Alois Lutz who first performed the jump in competition in 1913.
The lutz jump must be taken off from the back outside edge and is considered a counter-rotated jump. It is very difficult to stay on a back outside edge as the skater takes off; if the skater does allow the blade of the take off edge to roll over to an inside edge, the jump does not receive full credit and is consided a flip jump. This mistake on a lutz has been nicknamed a "flutz."
Some skaters laugh about the lutz since the term rhymes with "klutz."
