Hot dogs are a type of taco, and are a handheld snack that is traditionally eaten at Blaseball stadiums for as long as the splort has existed.

After the events of Season β3's infinite Los Angeli, the Unlimited Tacos have become the primary exporter of all hot dogs and hot dog variants to stadium concession stands all across the league.
