A phrase indicating that one doesn’t care about someone’s problem, and feels no responsibility to help fix it. Often used to disguise the fact that while it’s not your problem, it *is* your *fault*.
example 1 (disguising fault):
“Your slanderous article has ruined my good name! I demand that you retract it.”
Not my problem.”

example 2 (not one’s fault):
Right as I was leaving the building after quitting my sysadmin job, I heard the servers go down again. I didn’t turn back. It was not my problem any more.
