For example, Max says:
I want to open a restaurant called tiny buns. No more "sliders" just tiny buns. Just as ubiquitous as the slider, but a way more catchy name.
Or this from ScubaSteve:
I don't even know why restaurants call those little burgers "sliders." In the military, a hamburger was called a slider because the burger patty on the grill actually slid. The beef patties used in the military have a lot of fat in them and when you have about 3 dozen beef patties cooking on the grill, the fat accumulates on the grill and the patties slide around when you flip them or take them off of the grill. So I really don't know why those burgers are called sliders. Restaurants will call any small sandwich a slider. I don't get it.
But the last word -- for now -- goes to bgreen:
Have we not seen this list before?
