Someone who is known for constantly backing out on plans ("flaking"), often for reasons that are flimsy and/or somewhat insulting ("frosty").
"My friend was supposed to come visit me in the hospital after my round of chemo, but then she called at the last minute to say she couldn't afford to waste her gas on the drive up. I don't know what I was expecting anyway, she's totally frosted flakes."
