In Tagalog, whenever a person reminds you of a good thing that he or she did for you in a bid to make you do something good for them in return, it is called pagsusumbat or pagmumukha (of something). In Chabacano, we say sunsaca.
Santos' Chabacano dictionary defines sunsaca as to remind someone of earlier favor granted and favor is not reciprocated. He spells the word though as sonsaca (with an o). Most of the people that I know though would spell and pronounce this word as sunsaca (with a u). Surprisingly, Camins' dictionary does not have this word.
In my opinion, this is one of those words that young Chabacano speakers would probably identify as ondo Chabacano or deep Chabacano. I myself don't use this word a lot though know some people who love to use this word.
A possible candidate of the origin of sunsaca is the Spanish sonsacar. The problem with this theory is that the Spanish sonsacar has a totally different meaning from the Chabacano sunsaca.
Here is a sentence using the Chabacano sunsaca.
Chabacano: No tu sunsaca el maga bueno que ya hace tu para conmigo.
English: Don't flaunt the things that you did for me in my face.
You may also shorten this sentence by just saying no tu conmigo sunsaca and it will mean the same thing.
Another example of "sunsaca" is when a relative pays for your education and one day when you become successful, this relative tells you that you are where you are today because of him or her. Sounds familiar? This happens a lot in Filipino culture.
What about you? Do you use this word whenever you speak Chabacano?
