Poor Man's Black Velvet

Alcoholic beverage served at Irish Pubs consisting of hard cider on the bottom and Guinness stout on the top. Excellent for mid-day drinking since it doesn't make your breath smell like beer, tipping off your boss that you went to the pub for a pint (or two).

Also referred to as simply 'Poor Man's'

Barkeep: A Black & Tan for you today?

Me: Not today; lemme get a Poor Man's Black Velvet.

Barkeep: Ahhh... Better for summer, eh?

Me: Indeed.
