Hexekontenneaphobia

Exintenneaphobia (from Greek exinta, "sixty", and ennea, "nine") is the fear of number 69. The number may be the symbol of curse or irritation, as "The Curse of 69". Sufferers may get irritated when they see 69 a lot, especially from rather exotic sources, such as the amount of free space in gigabytes, number of friends online on facebook, number of likes to a page on facebook, scores achieved at the end of competition, and number of wins in sports seasons that last at least 150 games per team. Some may believe that 69-year olds can be cursed. 69-year old sufferers of exintenneaphobia may then suffer deprecorophobia.

In 1969, Cubs fans had this fear as a result of the, who had their 9-game lead in division in mid-August slipped away then missing the playoffs.
