false modesty

A vain or hypocritical pretense of holding a low or humble opinion of oneself, one's abilities, or one's circumstance so as to encourage others to say the opposite. There's no need for that false modesty here; you are fully aware of your success and achievement, and you don't need me to reaffirm it for you. I find her false modesty quite unbecoming. Ugh, Jake is the king of false modesty! He always says self-deprecating things and then waits for us tell him he's wrong.
