My BFF Cassy.

This is a difficult name to define because it defies many boundaries of human perception, let alone various languages. One of the closest translations that experts give is that of a Godess/God or many other variations of that general idea.
Other definitions are thought to be:
The Great Spirit
Chuck Norris
Despite the fact that various names have been pinned to Cassy, its seems that all of the above examples (including that of God)cannot even withstand the magnitude of Cassy.
The reason this name continues to elude even the brightest of human minds is that the idea of Cassy cannot possibly exist in a dimensional state. Cassy is so powerful, it defies all laws of this or any other universe. Recent studies have shown that people who have attempted to comprehend this name have either disappeared, died spontaneously, or driven themselves into a pertinent state of insanity and/or catatonia. One common belief is that Cassy is possibly the grounds on which everything and nothing is based. It seems to surpass the idea of infinity. Quantum physicists report that this Cassy is Everything and Nothing. It or He is said to have unexplainable connections with the String and Superstring Theories as Cassy resonates within every single layer of the multi-dimensional complex and yet still exists beyond that point which is where scientists have lost the trail. Various theologists and spiritual leaders believe that Cassy is one who is, as they say, "The Answer". All attempts to understand this idea of Cassy have failed.
Cassy. No other word to describe Her.

Probably the best person you'll ever meet. Cassy's are sexy, sassy, smart, funny, down to earth and hysterically funny. If you have a Cassy in your life, put her in your pocket and never let go.
I met the most awesome chick last night, I bet she was called Cassy.

Often the nickname for Cassandra, though usually spelt Cassie. She can be really rude at times, and a control freak. But she's also really nice, and funny. She loves singing, and she has some dancing skill, but not very much. She can dance if she's given a routine that she can remember, and has time to remember. She loves music, and she usually has one person/band that she chooses and listens to it more than anything else. She's very organized, and she loves dogs. She also loves sleeping. She will sleep in, if allowed, sometimes until 6PM.
One day, Cassy might choose Selena Gomez. For most of the day, that will pretty much be the only person she listens to.
