misbehavior, esp. in software, and esp. of misbehaviors which seem unfairly persistent (as though designed in by the imp of the perverse). Often theatrically elaborated: "Aiighhh! Fuck me with a piledriver and 16 feet of curare-tipped wrought-iron fence *and no lubricants*!" The phrase is sometimes heard abbreviated `FMH' in polite company.
[This entry is an extreme example of the hackish habit of coining elaborate and evocative terms for lossage. Here we see a quite self-conscious parody of mainstream expletives that has become a running gag in part of the hacker culture; it illustrates the hackish tendency to turn any situation, even one of extreme frustration, into an intellectual game (the point being, in this case, to creatively produce a long-winded description of the most anatomically absurd mental image possible --- the short forms implicitly allude to all the ridiculous long forms ever spoken). Scatological language is actually relatively uncommon among hackers, and there was some controversy over whether this entry ought to be included at all. As it reflects a live usage recognizably peculiar to the hacker culture, we feel it is in the hackish spirit of truthfulness and opposition to all forms of censorship to record it here. --- ESR & GLS]
