Lack of self-esteem and perception of your value in others eyes can lead to both. If you think you're not valued and your opinions not valued you will tend to add expletives (very, extremely) and absolutes to your language. Of course this can have the opposite effect on the listener. They know to dismiss the speaker (consciously or unconsciously). Similarly I've heard "arguments" from people on particular controversial topics and they have failed to put forward their view. The language is full of absolutely that and idiotic this but I'm still don't know which side of the argument they're on! John Lennon had a quote about this tendency. I've so far failed to find it.
