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
Mike: Bite marks... OH YEAH! That was from the CI stage
right?
Georgie: Yes, yes it was. Before you puked all over my room.
