Yuuko Moment 

Used to describe a series of bad luck, very bad luck or an unusual bad luck moment.

The term is named after the main character of the anime & manga, Yuuko Aioi, who is constantly suffering from back luck in many unusual ways.

I had a Yuuko moment today as my cat accidentally spilled my coffee and poured it everywhere on the floor and on my desk, which stained all of my paperwork.
