A dinner where you prepare with a random can of food without a label as a surprise, (reference to the movie Firefly, because River tore off the labels).
"What are we eating for dinner? I don't know, as she said it is firefly-themed dinner"
When you come home from blazing fat doobies and getting mega chonged you realise your whole family is over and they are having the family dinner while you are super chonged and your grandma says to you, “JOSH! Stop getting super chonged for the family dinner.”
