Project Bluebook 

The last publicly acknowledged USAF investigation into UFOs, which started in March 1952. Its aims were to find explanations for UFO sightings, to assess whether they were a threat to national security, and to determine if the UFOs used advanced technology from which the US could learn. Reports were collected, analyzed and filed according to their results. No-one noticed anything was wrong with the project until one of the people on the investigation team sent in his own sighting. It was filed, but when he wanted to refer back to his report, it had disappeared. He then alleged that any reports that were both unexplained and could cause public uproar were siphoned off out of Blue Book to somewhere else higher up in authority, a claim that ufologists now see as fact. Blue Book was wound up in 1969 as a result of the Condon Report and one of its investigators, Dr J. Allen Hynek, went on to form the first scientific based UFO group, the Center for UFO Studies, in 1973.

After closing Project Blue Book the US
Air Force has not publicly acknowledged any further interest in UFO sightings.

Cornerbag Blues 

When the amount of pot that you have left fills the corner of your baggie, usually about a days worth is left. Its consistency resembles a dry powder, not the soft, stinky nuggets they once were.

I need to call Mr. Nice Guy and get some chronic before I run out. I got a serious case of the Cornerbag Blues.

January Blues 

This is the funk that you enter when the holiday season is over. It starts on January 2nd and lasts at least until February 1st, sometimes until President's Day. It is an unpleasant time because the holiday season is over, spring is a ways off, the weather is cold and the only movies are lousy January movies. Super Bowl Sunday can be a good cure for this condition.

For a related condition see September Blues

There are no good movies out and the holidays are long over. Some friends and I are going to play some games to help fight the January Blues.

A marching drum corps full of angels and gods alike. Their beautiful brass sound shakes the stands and gives your heart a small orgasm. You will never regret watching the Bluecoats play. Especially the 2016 wink. That was just sexy

And in first place........ THE BLUECOATS!!!!!!

Midnight Blues 

A feeling of intense sadness and shame for the past or the dreading of events to come, stemming from overthinking as a result of sleep deprivation. This often occurs late at night, but can usually be remedied by simply sleeping.

“Babe I’ve been crying again, I miss you so much!”

“Just get some rest. You’ve got the midnight blues.”

Facebook Blues 

Facebook blues occurs after writing on someones wall, note, or status, and they don't respond. You wait and wait for a response constantly checking your Facebook to see if they have done so.

After the first day of hourly checking your facebook, you begin to facestalk them. This includes checking to see if they have commented on someone elses wall, status, or photos. As a last act of desperation, you send them a private message repeating the original post.

Your sadness resonates throughout Facebook until they respond, at which point you've gotten rid of the Facebook Blues.

She wrote on her crush's wall and waited a couple of days for a response. After the third day she was hit by a bad case of Facebook Blues; and, she felt sad that he had updated his status, but not responded to her comment.
