How it is used
In Recife and across much of the Northeast this labels a tightwad who has money but will not spend it; dictionaries also record a related sense of someone who sponges off other people's goodwill. It is clearly critical — do not say it to someone's face lightly.
Examples
Ele é tão pirangueiro que não quis pagar a conta.
He is so stingy that he didn't want to pay the bill.
