Non-Musical Masturbation on
Guitar.
A "textbook" lead guitar solo, usually denoted by repetitive, meaningless licks, played ad infinitum by less-than-stellar guitarists.
The first reference noted was by The Pretenders' original guitarist
Jimmy Honeyman-Scott in Guitar
Player magazine. He was describing the whole mess of lack-luster, over-charged, under-imagined, non-melodic guitar solos, and the players who practice that mind-numbing craft.
