Ang kulit niya!

If someone keeps asking you for something, even though you’ve already said no, then you can tell the person:
Makulit ka talaga!
You’re really such a pain in the ass.
Nakakainis ang kakulitan nila.

The Tagalog word makulit is often used in a light-hearted context to describe someone who is annoying in being repetitive, stubborn, or persistent in their asking questions or asking for a favor.
Kinulit nila ako hanggang sa umoo ako.
They just kept nagging me until I said yes.
