To properly end the "Movie Review Era" of this blog...I copied this from another website:
Bootleg: The first use of the phrase in the Omaha Herald in 1889- There is as much whisky consumed in Iowa now as there was before..."for medical purposes only," and on the boot-leg plan.
A bootleg refers to the long leather boots worn by cowboys in the Old West. They were used to store all manner of illicit goods, including an extra gun, a bowie knife, or a flask of moonshine. Incidentally, a bootleg play in football refers to quarterback running pattern that entails making a sharp perpendicular turn around the tight end.
It's now used to refer to anything illegal, unauthorized, and unregulated, like concert recordings and titles for completely-unrelated-to-the-movie blog posts.
