For example, someone who has gone "Full Williams" in training is pushing their body into working out to the highest level of intensity.

Someone may be described as Full Williams if having walked into a camera shop, with the intention of buying a new compact camera for family snaps, they subsequently leave with a top of the range SLR setup, complete with an array of Lenses, Filters, lights, reflectors, and associated paraphernalia.
