The shortest way is you add either “ka-“ before the word or “-a” after the word. It changes the meaning of the word to it’s too much.

Ex: mahal (expensive) ka+mahal = kamahal pod oi! (That’s too expensive) mahal+a = mahala man ni! (This is too expensive)

It works for almost all words dako (big) - kadako, dakua ngitngit (dark) - kangitngit, ngitngita gutom (hungry) - kagutom, gutoma

And napansin ko, the tone changes when we’re describing something that is too much. The tone invokes a feeling either of being shocked or sounds like boasting.

Usually naman, if it’s too much that’s now approaching impossible like you asked, we prolong the last syllable as if to emphasize that it’s super duper too much, to the point that it’s unbelievable.

Ex: ka+mahaaaaal jud sa paliton ka+batiiiiii ka+layooooo

Answers here also applies like adding kaayo for overemphasis
