Blah is defined as a belief of complete emptyness in Instant messages like AIM when its really full of emotions that the individual is afraid to realize because they feel that they need to hide their emotions because they dont feel its right to say them at the time; or the fact that they might have hid it from themselves for what they felt was their own good
John: So what do you think about me right now as more than a friend?

John: What is that to mean?
Elizabeth: Nothing at all it means its i dont know what it means

It lightens up any serious situation and usage of the word has become ubiquitous in Christchurch, New Zealand.
