where did the term sliders for hamburgers come from
Slider (sandwich) The term was originally used to describe the onion-steamed small burgers at White Castle restaurants[citation needed]. White Castle trademarked the spelling variant "Slyder" and used it between 1985 and 2009.[3]
Polka dot It is likely that the term originated in popularity of polka dance at the time the pattern became fashionable, just as many other products and fashions of the era also adopted the "polka" name.[1]
Bracket Forms include round (also called "parentheses"), square, curly (also called "braces"), and angle brackets (also called "chevrons"); and various other pairs of symbols.
Shekhinah This term does not occur in the Bible, and is from rabbinic literature.[2]:148[3][4]
