The act or action of asking someone something so many times that it defies the most complex form of nagging and becomes harrassment.
First time:" Hey are you still jamming out? You should play sometime"
Second time:" I heard your still playing, I want to hear"
Third time" " You still haven't let me hear you play"
Two-hundred and sixty-seventh time: " Hey-"
Victim: " Quit Harrasking me!!"
