. What does KIK mean

The two most likely possibilities for the meaning of "KIK" are a typo or Kik Messenger:

KIK is a very common typo for when someone is trying to type LOL, or Laughing Out Loud (the fact that they may actually be laughing out loud may be a contributing factor to this typo, though some suggest that late night partying is really the most common reason).

Kik Messenger

This is a free cross-platform app available for iPhone, iPod Touch, iPad, Android, and Blackberry that allows you to message your friends in real time, as well as share photos.

The founder of Kik Interactive (makers of the messenger) just gave away $25,000 each to four startup companies seeking venture capital: SciGit, Matinee, Weston Expressions, and Flockwire (also known as “Inflo”).
