Origin

The phrase is one of the many derogatory ones that originated in America. The implication of the insult is that the person has some part of the brain missing. Deck is a reference to a deck of cards.

Our many users suggested that the phrase was coined in 1965 by George Denis Patrick Carlin – an American stand-up comedian.

George Carlin – Stand Up Routine – The Merv Griffin show, 1965:

“Thank you very much golly! I think we all realize he’s not playing with a full deck folks.”

Then the audience burst into laughter. And the phrase caused the biggest laugh in the show.

Play, Stupid
