spitting & throwing

There is a subtle difference between 'spitting' and 'throwing'; before 'spitting' the object should have been welcomed to come inside the mouth and to take that step the object must have been a thing of desire, and consequently 'spitting' is more painful version of expulsion, and it is like 180 degree turn around compared to throwing, which is lot more casual act :-)

What made me think about this?
Peter Murphy's song "cuts you up" made me dwell deeper in to spitting. Note that his songs does not convey the same meaning as I described above.

Personally I associate this song with frustration that one undergoes while learning any creative thing. My favorite lines are.... 'it takes you in and spits you out' when you start feeling that you know everything.

Cuts you up - Peter Murphy
You know the way it throws about.
It takes you in and spits you out
It spits you out when you desire
to conquer it, to feel you're higher
