It's the opposite of being humbled. It's amusing (and a little disturbing) that it can be dressed up the way it is.
EDIT: messed up some grammar... this mistake has humbled me.
Of course, even this approach will have its own shelf life — meaning that, if used widely, it will also become a parody of itself.
Pretending to be humbled is basically lying about the amount of recognition you receive in the hopes that new people will be tricked to really consider you important. Perhaps similar to tagging everything with #blessed on instagram.
"I'm so humbled and honored and surprised to be/serve as X and I want to thank my parents / offer mentoring to the less fortunate of you" often after aggressive pursuit, self-nomination or unacknowledged massive help / connections to get whatever the thing was.
