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.
Their nagging is so irritating.

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.
