Quite often a professional musician, a professional "that guy" is hired to be a scape goat for lameness and criticism. They are the tried and true wingmen for all those who can't quite cut it in public.
Holy crap, Taylor Swifts guitarist is totally a Professional "That Guy". No Johnny, your just a regular that guy.
