Also known as the CI stage, it is the state of drunkeness before the drunkee starts throwing up, but after the stage where they are merely tipsy. Short for cheerfully inebriated.

People in the CI stage are very hyper and random, often times a bit horny. They normally remember things that happened in the CI stage the next day, and are semi in control of what they are doing.
Georgie: Mike I found your bite marks on my desk xD

Georgie: Yes, yes it was. Before you puked all over my room.
