Pet Is Birth 

A common catch-cry of college students across New Zealand. It is used when there is nothing else to say in the class-room environment eg, akward silence or just the chance to just get attention.
It's origins are largely unknown but it is suggested that it started in the year 10 KingsWay School Drama class in the year 2004.
'Pet Is birth' is a classic example of a random concept that never died down. It spread like wildfire it maybe one day it will be written down in the annals of time itself.

Mrs Robotham! Pet Is birth!
