It is often tricky to say the word 'fast' in Chabacano. Often it depends on the context on how you say the word 'fast' in Chabacano. There are five ways I can think of to say the word 'fast' in Chabacano.
Paspas: This word comes from the Cebuano language. This, I think, is the most common word for 'fast' in Chabacano, especially among young Chabacano speakers.
Todas: The word todas is defined as in full force or with much force by the Chabacano dictionary of Rolando Arquiza Santos (2010). This word is sometimes also used to mean 'fast' or 'loud' by other people but these definitions don’t exist in Santos’ Chabacano dictionary because these definitions are very colloquial. Camins’ Chabacano dictionary was published more than twenty years before Santos’ does not have the word todas.
Pronto: This word comes from the Spanish language and it also means quick or fast in that language. In Italian, the word pronto also exists and means fast as well. Colloquially, pronto can also mean easy in Chabacano. Camins' dictionary defines pronto as quick and prompt while Santos' defines it as fast, soon, and quick.
Corre: Aside from 'to run', this word can also mean 'fast'. The stress on this word falls on the letter o if it's a noun.
Rapido: The word rapido is markedly absent in Camins’ dictionary. It is, however, present in the dictionary of Rolando Arquiza Santos. I have to say though that I have never heard this word used in the Chabacano language. It might have been used in the past though or by old people. Rapido is the common Spanish word for the adjective fast.
Ligero: The word ligero is a Bien Chabacano word meaning 'fast'. You will be hard pressed to find young Chabacano speakers who know this word. It is present in both Camins' and Santos' Chabacano dictionaries.
