parao en 30
To be flush with cash, loaded, or living large. It refers to the feeling of being financially set on payday, which is typically the 30th of the month (In the Dominican Republic, salaries are commonly paid on the 15th and 30th).
When you get paid on the 30th, only that day are you parao en 30 with enough money to go out and party like you should.
