this is a combination of delicious and hellacious that describes something that is extremely tasty or pleasurably spicy or hot but that you know you shouldn't be eating because of its poor effects on your health, especially digestion.
Man, those hot wings are dellacious, but I can't help myself. They taste so damn good, and I know I'll be tearin' up the toilet in a few hours.
