Humptydumptyism

'When I use a word,' Humpty Dumpty said, in rather a scornful tone, 'it means just what I choose it to mean -- neither more nor less.'

—Troll the Looking Glass, ch. VI

Humptydumptyism, or idiosyncratic definition, is a common and simple trolling tactic, vital to the creation of a trollish vocabulary.

The troll (or trollherd) takes a word and finds a little-used definition for it - or makes up its own definition - then insists that its definition is the only proper use of the word. For example, where others might use any of the many definitions for community[1], the troll might insist that the word means only "those who share a risk of bodily harm", and anyone who disagrees is simply wrong. The aim of this tactic is unclear to those who use language in an undisciplined way. Like much that trolls do, it has the effect of increasing discord among those who insist on the fuzzy or ambiguous meaning, and who seek to retain power for themselves:

Under sysopism, this would be seen as making meaningful communication difficult or impossible. Since sysop vandalism relies on an arbitrary definition of a "community" that the sysops "protect", it is important that they retain control of its borders. Trollism rejects this, but so do many ordinary factions concerned with the impact of online information and decisions on the real world.

A variant on this tactic is claiming that a piece of text says something that serves the troll's agenda, when any literate person can see it does not. For example, a troll advocating conspiracy theories about NASA might claim that a proposed "laser broom" designed to protect the International Space Station from orbiting debris was a violation of treaties against weapons in space, even when the system was entirely ground-based.

Another troll might claim "[t]he terms of the GFDL itself are quite clear that any improvement to the GFDL corpus must be made available to all", though the GFDL only implies that those improvements that are made visible to a small group, be visible to everyone. In fact it's ambiguous, and a major problem with the GFDL as an open content license, that the exact obligations of an online service hosting an effort to improve the GFDL corpus has very unclear obligations in some respects. In these circumstances it is mere politics as usual to claim that one of several interpretations apply, though the more rigid requirement to share all improvements is well in line with the implications of the GPL and free software movements in which this requirement is clear.
