A word abbreviated from Progressively Hard-as-a-Rock, which also is loosely translates to Progressive Rock. This genre of music, as well as bands dedicated to it, is known for its tendency to give listeners the most intense orgasms known to humankind. Musicians who play prog are thought to be Trans-dimensional Gods from another world, who have a zenith of skill higher than any other being in existence, whether it be of imagination or reality.
Some are examples of Prog Rock are as follows: Rush, the unearthly projective illusion of raw musical skill; Dream Theater, the offspring of Rush, whom are considered above all others in complexity; Pink Floyd, the acid trip you'll never forget, complete with the only side effects being longer and more intense orgasms; Porcupine Tree, the ominous shadow of pure musical pleasure. Please remember these four super-organism colonies are an obscenely minuscule fraction of the entire entity that is the Progressive Realm.

Get the Prog Rock mug.
a genre created for guitarists with massive egos and small packages that compensate by overuse of excessive amounts of footpedals and fans who analyse each aspect of a song
typical person: nothing like a good ol' rock track with a sweet guitar solo!

Prog-fan: rock track? or prog rock track? what pedals did he use? Delay? Flanger? Chorus? Was it in D minor? was he in an alternate tuning?

typical person: ... he played a red guitar? o.O
