1. Blue Monday is the most depressing day of the year, calculated by Dr. Cliff Arnall, a researcher at the University of Cardiff's Center for Lifelong Learning.
Factors used to calculate the date included weather conditions, debt level, time since Christmas, time since failing our New Year's resolutions, low motivation and feeling the need to take action.

In 2005 the date was calculated as January 24th, in 2006 it was January 23rd, and in 2007 it was January 22nd.

2. A song by the hard rock band Orgy from their album Candy Ass.

This is an old term dating back at least 100 years. My grandmother from Eastern Texas used it quite often to describe an uncouth person. I believe it refers to persons who probably didn't have an out-house or toilet, then when they dropped their pants and stooped down to evacuate their bowels, they would sometime hit the back of their shoes or boots. Of course, they probably just as often hit their pants.

Slang for an idiot, a despicable person.

An asshole; a despicable, loathesome person.

A piece of human filth that thinks he is superior to everyone else on the planet.

An obnoxious person who is generally disliked.
