Worf is the Klingon security officer from Star Trek the Next Generation. He was a big, tough guy with plenty of battle experience. But it seemed like in every episode to prove the Big Bad's bonafides as a dangerous opponent it would fight and take out Worf. Thus any tough character who gets routinely flattened is described as 'the Worf Effect'.
