Double jeopardy is what happens when you eat really spicy foot. First your mouth is put in jeopardy by the fiery hotness of what your are eating... Double jeopardy inevitably occurs the next day while the hotness is on its way out.

Kev: I know dude, that was awesome!
Mike: I thought so...until double jeopardy hit me today.
