(SF fandom, originally as mutation of HHOK, "Ha Ha Only
Kidding") A phrase (often seen abbreviated as HHOS) that aptly
captures the flavour of much hacker discourse. Applied
especially to parodies, absurdities, and ironic jokes that are
both intended and perceived to contain a possibly disquieting
amount of truth, or truths that are constructed on in-joke and
self-parody.
The
Jargon File contains many examples of ha-ha-only-serious
in both form and content. Indeed, the entirety of hacker
culture is often perceived as ha-ha-only-serious by hackers
themselves; to take it either too lightly or too seriously
marks a person as an outsider, a
wannabee, or in
larvalstage. For further enlightenment on this subject, consult
