Hoo boy, black licorice sucks. It's not just kinda-bad, it's not just mildly bad. It actually has a hostile taste. It's a flavor that has you groping for an emergency beverage. It's foul.
Now if I licked a car tire, that would be foul too. But here's the difference. The car tire isn't in the candy aisle. There are things that taste worse than black licorice I grant you, but there's nothing that exceeds black licorice in the disparity between promised taste and actual taste. Nobody thinks a handful of mouse droppings is going to taste any good. But if we bagged them and put them next to the Snickers and called them Mouseychews then I think you'd be setting unrealistic expectations.
