dirty double

The act of burping and farting in rapid succession, one after the other.

Legends tell of a 'terrifying triple' which also includes a sneeze, but this is said to herald the apocalypse and one's utter destruction.
Just before going out to the bar, Jill burped and farted, a so-called "dirty double" and then exclaimed: "NOW I'm ready to go!"
