It's an acronym for Cry About It. Best used after someone has told a long story about how sad and miserable their life is.
Sad KID: oh my god! I'm so depressed right now, my girlfriend just broke up with me and my parents wont let me go to the Fall Out Boy concert. I hate my life!

A creature that originates from the north east but moves down south for warmer weather and a reduction in pollution. They can be identified by having rabbit like hair, it is a peaceful animal but can get very agressive when agitated by magpies or black cats. It is best to avoid in the wild as they may be hungry and attack.
Look at that little cai over there, isn't it cute!
