Re: Burger slinger?
"The name originated in the 1940s, when sailors in the U.S. Navy would refer to mini-burgers as "sliders" because of their extreme greasiness. In just one or two bites, the burger would just slide right down! The slider was first created at White Castle, a popular American fast food chain restaurant."
And according to my dad, said burgers continued their entire journey in the same manner.
