Define Widdly-woo Meaning

Widdly-Woo
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.

"I got really tired of the ol' Widdly-Woo solos played by the funny-hat blues cats down at the local Jam Night"
