It means no one is ready to do efforts for this answer.
Why do you have to get rude? There have been many answers in this thread, so I don't think I agree with your statement.
I repeat what Aachu asked: where did you come across it? Can you not give any context?
You mentioned not finding it in
one dictionary. Have you tried other dictionaries? There are plenty on line. Have you tried googling it up? Have you tried the COCA?
You're wasting more time playing the enigmatic here than if you'd tried any of my suggestions above.
