Slang term for Mogen David wine, especially the fortified-wine MD 20/20 variety. The MD stands for Mogen David. It was shortened to MD for their line of bum wines to differentiate between their more respectable (if no less nasty) line of kosher wines.

Contrary to popular myth, there has never been a wine sold under the name Mad Dog.
