It's the Trinidadian way of saying "asshole"
caca means shit. Literally shit-hole.

It can also be used to refer to someone in a derogatory manner.
1. That man smelling like my cacahole! (the word "is" is omitted to reflect slang/dialect)

2. Imagine he went to the police to report that his neighbour stole his weed. That man is a cacahole!

3. He only giving that woman food and his money but she does not care about him in any way. He is making himself look like a cacahole
