A group of rather friendly and outgoing students at the Illinois Mathematics and Science Academy who spend some (if not a majority) of their time sitting, laying, sleeping, or even standing on or in the vicinity of the area near the History Office containing a group of blue couches (dubbed the "Couches"). Couchies tend to be friendly, open-minded, humorous, knowledgeable, outgoing, and sometimes even opinionated. "Couchies" is sometimes used as a degrading term for this group of people (however, not as much in recent years), and the name stuck.
Those couchies are fun to be around!

Are you a couchie? Yes, I am.

Get the Couchies mug.
A college roommate who always spends the night on the common room couch, and never seems to set foot in his bedroom. Covers the couch in dandruff and leaves a lingering odor of nut funk. Important: this roommate does not pass out on the couch. He intentionally sleeps there; pillows, blankets and all. He may fall asleep while watching one of your DVDs. When you wake up and stumble out of your bedroom at 8 AM, he will be snoring away and the TV will be on. If you turn the TV off, he will wake up and mumble something about how he wasn't sleeping and that he was watching whatever show you turned off. If this roommate's condition is not taken care of early enough, he will move his computer and all his stuff out of his room and into the common area.
"Yo, did see you couchy out there again this morning? I know he said he wasn't sleepin', but I turned the TV off anyways."

The plural form of "couch", which is defined as anything included in the same family of furniture as sofa, loveseat, but excluding chair-and-a-half. This alternative spelling of the plural form is a direct result of the increasing use of the "i" suffix to many words in elite engineering institutes and universities in classes. The more couchi, the better.
That house has 4 couchi facing the big screen tv. It's so dank!!!
