KIK

KIK is a common mistyping of "LOL" meant to convey laughter. Since it is a common typo, some people use it intentionally when messaging online or when texting.

The reason people often mistype KIK is because of the proximity of the "K" and "I" keys to the "L" and the "O" keys on a keyboard. They may have fat fingers or are in a rush and don't check the three letters they typed before sending the message. For example, your friend may send "kik" in response to your funny video as they are about to start driving.
