Brokers Reserve is an American Blended Whiskey that is 40% alc/vol. It cost between 6 and 7 dollars for a 5th. People generally buy it when they are broke or are cheap. People call it broke-ass for short.
Dude #1 "Ahh..Man your drinking broke-ass brokers?"
Dude #2 "Yeah I only had 7 dollars in my bank account."
