What is Friday the 13th..?

According to Wikipedia:

Friday the 13th occurs when the thirteenth day of a month falls on a Friday, which Superstition holds to be a day of bad luck . In the Gregorian Calender, this day occurs at least once, but at most three times a year. Any month's 13th day will fall on a Friday if the month starts on a Sunday.

Do the terms triskaidekaphobia and paraskevidekatriaphobia or friggatriskaidekaphobia mean anything to you? Have you come across these terms?

The Phobia fear of Friday the 13th is called friggatriskaidekaphobia (Frigga being the name of the Norse goddess for whom "Friday" is named and triskaidekaphobia meaning fear of the number thirteen), or paraskevidekatriaphobia a concatenation of the Greek words Paraskeví (Παρασκευή, meaning "Friday"), and dekatreís (δεκατρείς, meaning "thirteen") attached to phobía (φοβία, from phóbos, φόβος, meaning "fear").Horribly long words huh?

 

Triskaidekaphobia means fear of the number 13.

Paraskevidekatriaphobia is the fear of Friday the 13th.

Friggatriskaidekaphobia is also fear of Friday the 13th.

Triskaidekaphobiathat THIS is a REAL Psychological Disorders phobia that gets made fun of all the time without anyone batting an eye… Why is that?  Why is it okay to make fun of people with phobias like Friggatriskaidekaphobia that affect a great many people? 

I do not have a fear of Friday the 13th, rather my fear gets made fun of all the time.
