A missed call is a telephone call that is deliberately terminated by the caller before being answered by its intended recipient, in order to communicate a pre-agreed message without paying the cost of a call. For example, a group of friends may agree that two missed calls in succession means "I am running late". The practice is common in South Asia, the Philippines and Africa.
There can only be four pre-arranged messages because phones only ring four times in South Asia.

I must say, not having had the courtesy to be informed of the content of the motion, and having presented the House with a request twice today and having been refused twice by the government, the Progressive Conservatives and the separatists, I find it totally irresponsible at this time of the night that the government plays this little dumb game with the House of Commons.
The government has only made one refusal today.
