Trishia 

Trishia is such an amazing, talented, intelligent person! She’s very nice most of the times but can get an attitude when hungry or tired. So take care of her, and she’ll take care of you. She’s loyal, caring and loving. Don’t loose her.

Boy 1: I have never met anyone like Trishia before!
Boy 2: Yeah she’s pretty amazing

triskaidekaphilia

Obsession with the number thirteen.

Triskaidekaphiles smile when they walk up thirteen steps, or a ball bounces thirteen times, or it's thirteen minutes past 1pm, or their room is on the 13th floor, or the change in their pocket somehow adds up to a multiple of 13, or the numbers in the licence plate of the car ahead add up to 13, or they find out that the Apollo 13 mission failed on April 13th, or they were born on the 13th, or they look closely at the Great Seal of the United States, or it's the 13th of the month, or there are thirteen people in a room, or someone bakes them a baker's dozen , or they can just about think up thirteen examples of triskaidekaphilia.

The word is greek for 'thirteen love'.

It's the opposite of triskaidekaphobia, which is where people have a problem with the number thirteen. Which is just weird.

Triskaidekaphobia 

Fear of the number 13.

The year 1998 was a bad for triskaidekaphobics. Strictly, the word does refer only to fear of the number 13, but it’s often extended to mean fear of the inauspicious date Friday 13th. That year was one of the comparatively rare ones in which that date turned up three times. Every year has at least one Friday 13th, but in each of the 28-year cycles of our calendar there are four years that have three of them. The only consolation I can offer to those affected is that there won’t be another for 11 years. But then we shall have three in short order: 2009, 2012 and 2015. The word’s origins are all Greek, from tris, “three”, kai, “and”, deka, “ten” (so making thirteen), plus phobia, “fear, flight”. The word is a modern formation, dating only from 1911 (it first appeared in I H Coriat’s Abnormal Psychology). Though it has a serious use in psychology, it seems to exist mostly to provide an opportunity for people like me to show off weird words from classical languages.

I'm triskaidekaphobic(no I'm not).

Triskaidekaphobia 

This is fear of the number 13. It goes back to the time of Christ where there were 13 at the last supper and is a surprisingly common fear. Hotels rarely have a 13th floor and many people will not be part of a group of 13; Winston Churchill, for example, refused to dine at a table with 13 guests.

Many people suffer from triskaidekaphobia
