A reality hacker is an urban spelunker. "Building hacker" is a better term than "reality hacker" for participants in urban exploration activity. Using the definition of hacker that the mainstream media uses, a reality hacker is like a computer hacker but instead of hacking into computers, a reality hacker "hacks" (enters without authorization, trespasses, explores) in real life.
A reality hacker is an explorer of the underlying reality of existence; using any tools available. Science is an important subset of reality hacking. Classical mysticism is another. The hacking part means, as with other forms of hacking, learning of capabilities that the ordinary user may never realize are in the system. This uses the definition of hacker used by computer programmers, not the mainstream media.
Among hackers, though, slang has a subtler aspect, paralleled perhaps in the slang of jazz musicians and some kinds of fine artists but hard to detect in most technical or scientific cultures; parts of it are code for shared states of consciousness.
Hacker slang is unusually rich in implications of this kind, of overtones and undertones that illuminate the hackish psyche.
Hackers, as a rule, love wordplay and are very conscious and inventive in their use of language.
