Top Definition
A failure ( or fail ) so disastrous that it achieves the total reverse of what was originally planned because the effect of an action has become so dissociated from the intent behind it.

A reference to the Clint Eastwood movie 'The Eiger Sanction', in which Clint, an assassin, is so convinced his target is a member of a teem of mountaineers climbing the Eiger - he just doesn't know which one. So he murders all of them just to make bloody sure - then finds out he was wrong all along, like a moron, because it's been obvious as hell all along who the real bad guy is.
HIS LIFELINE - held by the assassin he's been hunting. Eiger Fail.
