Doctor 40 

Mogen David 20/20 wine. Also called Mad Dog or Mad Dog 20/20. It is a low end, cheap wine; a favorite of winos and young men who think it is cool to get drunk on the cheapest wine that is available. It is cheap and strong. It has an 18% alcohol content, even though many think the name is derived from an alcohol content of 20%

I'm in need of a buzz, but I don't have much cash. Let's get some Doctor 40 for what ails us.
