what does hes not playing with a full deck mean

There are a lot of confusing idioms that are used in the English language today. For instance, you may be having a conversation about someone when the person you’re talking to tells you that “he’s not playing with a full deck.” Do you know what they mean when they say this to you?

Origin of the Phrase

The phrase “he’s not playing with a full deck” is one of many derogatory idioms that have originated in America. This insult implicates that a person is missing part of their brain. Some people say that this phrase originated from a time period when there was a tax on the Ace of Spades. During this time people would buy a deck of cards without it so that they wouldn’t have to pay this tax. However, most games would require a full deck of 52 cards so these people were thought to be foolish or not “playing with a full deck.”

One thing is for certain, the American stand-up comedian George Denis Patrick Carlin used the phrase in his stand-up routine on the Merv Griffin show in 1965. He’s quoted as saying, “Thank you very much golly! I think we all realize he’s not playing with a full deck folks.”

Some people don’t think that this phrase is rude at all. This is because when you’re playing a game of poker and you don’t have a full deck you’re using this phrase literally to mean that you’re not playing with a full deck of cards. This doesn’t mean that you’re crazy. It merely means that you’re missing at least one card.

Even if the expression isn’t being used to mean that someone is stupid or crazy it could still come across as being arrogant. It clearly depends on how it’s being said because when you read this phrase it could come across as either a simple statement of fact or as a put-down. This is why it’s so important to carefully edit your writing to ensure that the phrasing isn’t questionable when you’re using idioms such as this one.

Meaning of the Phrase

When you say that someone is “not playing with a full deck” you have to look at the context that surrounds this phrase to truly understand what someone means by saying it. Looking at the meaning of its words on an individual basis won’t tell you what the phrase itself means here. This is because the phrase is an idiom. Therefore the phrase has a complicated meaning. They’re used to allude to something different than what they’d mean if you were to take them literally.

Although you can trace the origin of this idiom back to 1965 it gained popularity in the United States during the 1980s. It’s a derogatory expression that’s used to mean that someone isn’t very smart or to allude that someone “has a bit missing,” or “isn’t all there.” In other words, the person who’s on the receiving end of this jocular insult was missing part of their brain or lacking in their sanity. Here the deck was referencing a deck of cards. Anyone who wasn’t playing with a full deck of cards wasn’t expected to do very well.

Some of the synonyms that could also be used here include:

  • Not mentally sound
  • Stupid
  • Dimwitted
  • Crazy
  • Mentally deranged
