Any super-lame way of doing things that has not yet been codified into being a [[science]].  Every form of knowledge one is too lazy to investigate is magic.

Magic is not to be confused with [[chaos]] or [[improbability]].  Magic is bound by rules, even if these are often poorly understood and can be shored up by a 'theory' of how actions work and why they do what they do, whereas chaos, and improbability apparently cannot.((One aspect of improbability, however, __is__ predictable:  The [[Improbability Drive]] will kick your ass.)) ((So will Paul Daniels if you keep dissing magic)) Plus, magic is blue, chaos is the reddish-black of dimming coals, and Improbability is green. Duh.

Some people have been known to use magic: [[Cheshire Cat]], [[Rosin]], [[Lady Akitsu|Akitsu]], [[Harry Dresden]], [[Kuroiten]], [[Paul Lo]], [[Merlin]] . . . ((Add names to the list?))
