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
