Triskaidekaphobia is the irrational fear of the number 13. Paraskevidekatriaphobia is the fear of Friday the 13th. (also friggatriskaidekaphobia).
Pardon me if I remain firmly in the TGIF* camp. For the rest of you, I guess there's always phobophobia - the fear of fear.
Happy Friday the 13th! Pay no attention to the hail, tornadoes and violent storms in sunny California preceding this memorable day...
*Thank God it's Friday, not "Toes Go In First"
