Ex-governor of Alaska and ex-vice presidential canidate who refuses to just fade away quitely- what with her book tours, TV deals, and that stupid "tea party". Continues to voice her opinion on everything as if her opinion really matters anymore.
Why won't Failin' Palin just shut up and go away already! She didn't win the vice presidency (thank goodness) and she's not even a governor anymore.
This term describes the nightly experience of those unfortunate schmucks who just absolutely cannot fucking fall asleep, no matter how much thrashing around in bed they do or how much ruminating over past mistakes they indulge in. Instead of falling asleep, an insomniac is simply failing asleep.
