A crappy
throw, toss, etc., where the person tossing the object misjudges the
throw and completely misses the intended recipient,
target, etc.
Lorenzo: "T-Bone, toss me a can of beer!"
T-Bone: "Here ya go!" (Throws beer 3 feet to the left of
Lorenzo)
Lorenzo: "Dude, that was an Underhanded Mustard Russian if I've ever seen one!!!!! Now the beer is ruined!"
