What does "Kik" stand for in a text message?

The word "Kik" commonly appears in text messages in short phrases such as "What's your Kik?" and "Kik me," both of which refer to Kik, the free instant messaging application for mobile devices. Developed by Kik Interactive, Kik is available for iOS, Android and Windows Phone operating systems.

Kik uses a phone's data plan or Wi-Fi connection to send and receive text messages and other forms of media. Kik's website claims that the messaging app has over 240 million users as of December 2015. Kik has recently seen a surge in popularity, having received a $50 million investment from the Chinese Internet company Tencent in August 2015.
