It could be a variation of these words:
* "Pang-tanggi": This literally translates to "for refusal" and can be used in the context of rejecting something.
* "Pintang-tanggi": This translates to "painted refusal" and is likely used in a metaphorical context, referring to something that is clearly rejected or denied.
* "Pangtanggi": This is another possible spelling, but again, it's not a commonly used word.
Without more context, it's hard to give a precise definition of "pantangi". If you could provide more information about how you encountered this word, I might be able to help you understand its meaning better.
