New word used for when you're having an IM conversation, like on msn, and a parent or sibling starts observing what you're writing.
You type 'kigr' so that they know not to swear or talk about something you wouldnt want them to see.
Conversation on IM:
Jessica: hey john :)
John: hey jessica, so i hear you're having a party at your house when your parents go away for the weekend
(Jessicas mum walks past the computer and stops to see what she's writing)
John:oh wait i think that was someone else
Jessica: yeah must be
(Jessicas mum walks off)
Jessica: phew that was a close one
