From the song by Nick Cave & the Bad Seeds, used to describe the depressed feeling you get about the modern world in general. An abattoir is a slaughterhouse, so the term, in a more in depth way, means you feel the world is lining itself up for slaughter, much like cows do at a slaughterhouse.
Man 1: Hey, are you all right? You've seemed kinda depressed lately.
Man 2: Oh, it's okay, I've just got a case of abattoir blues.

Yuji Kaido was diagnosed with a serious disease (the "B-cells") and cryogenically frozen. He wakes up more than 20 years later and Earth is nothing like what he remembers. A race of alien bugs called the Blue have taken over the planet, and a few select humans have retreated to the space station Second Earth. Yuji is taken back to Second Earth, where he learns that he and the other sleepers will be instrumental in defeating the Blue. And his relationship with one member of the recovery squad only serves to complicate things.
Blue Gender is an excellent 26 episode anime series. In 2003, Blue Gender was released in the U.S. as part of Cartoon Network's Adult Swim, though it had originally been planned for Toonami, and was thus edited to remove its graphic violence, nudity, and sex scenes.

The work Blue money is used in mostly hip/hop rap songs. The word refers to 100$ bills. If you look closely at a 100$ bill you will find a blue line that goes up and down the bill.

The depressed feeling you get after going to a convention and seeing friends. The afflicted usually desperately text or call everyone they know from the convention, spend ridiculous amounts of time on facebook and forums where they find their friends from the convention, and go over every memory hundreds of times.
Man, now that PortCon is over I have some major postcon blues.
I'm dreading the postcon blues feeling I'll have next week.
