Importunity
Lack of modesty; shamelessness.

And he from within shall answer and say, Trouble me not: the door is now shut, and my children are with me in bed; I cannot rise and give thee. I say unto you, Though he will not rise and give him, because he is his friend, yet because of his IMPORTUNITY he will rise and give him as many as he needeth. ( Luke 11:7-8 )
