- hacker humour — A distinctive style of shared intellectual humour found among hackers, having the following marked characteristics: 1. Fascination with form-vs.-content jokes, paradoxes, and humour having to do with confusion of metalevels (see meta). One way to make a hacker laugh: hold a red index card in front of him/her with "GREEN" written on it, or vice-versa (note, however, that this is funny only the first time). 2. Elaborate deadpan parodies of large intellectual constructs, such as specifications (see write-only memory), standards documents, language descriptions (see INTERCAL), and even entire scientific theories (see quantum bogodynamics, computron). 3. Jokes that involve screwily precise reasoning from bizarre, ludicrous, or just grossly counter-intuitive premises. 4. Fascination with puns and wordplay. 5. A fondness for apparently mindless humour with subversive currents of intelligence in it - for example, old Warner Brothers and Rocky & Bullwinkle cartoons, the Marx brothers, the early B-52s, and Monty Python's Flying Circus. Humour that combines this trait with elements of high camp and slapstick is especially favoured. 6.

See also filk and retrocomputing.
