Fey Luck
The type of luck whenever everything seems to be going right, then all of a sudden everything goes to hell in a handbasket at the worst possible moment.
Hey man how did that big sale go today. Well it was going good but then whenever they went to sign the papers I coudn't find them. I must have put them on top of the car and they blew away whenever I left the office. Man that right there is fey luck right there.
