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 or stubborn or unflagging in their asking questions or asking for a favor.

They just kept nagging at me until I said yes.
